SHIPPING

We put a strong emphasis on fantastic shipping practices. After learning from shipping thousands of guitars, we have come up with a few shipping rules:

  1. We only ship instruments and amps with FedEx or UPS.
  2. All shipments (besides inexpensive accessories) are shipped with a signature required, no exceptions.  
  3. Instruments are packed so there is no movement in the outer box, and/or inside the case (this is the key!).
  4. Plenty of tape!
  5. Always have shipments on the truck the same (by 2pm ET) or next day.

You will receive a tracking number as soon as your order ships. Please note: Tracking numbers usually take 24 hours before they appear in FedEx/UPS/USPS systems.  All delivery changes (hold for pickup, address change, etc.) must be requested before your purchase leaves our store, otherwise, they are the responsibility of the customer.

RETURNS

Due to a change in refund policy by our payment processors and PayPal, we must update our return policy to include a 3-10% restocking fee in some cases (see item 4 and 8).

  1. We ALWAYS stand behind our products. Call us with ANY issues - we want to help you! If an item is damaged in shipping or the wrong item is shipped, we will always accept a return at $0 cost to you (we will cover return shipping, and charge no restocking fee no matter the payment method, etc) AND/OR offer a partial refund to fully cover the issue. We need to be notified of shipping damage or issues with the item within 48 hours of item receipt in order to process your request in a timely manner. 
  2. All new AND used items are fully inspected, setup, and maintained for full 100% playability and electronic functionality by our in-house tech when they ship. If your guitar starts buzzing after a couple weeks, CALL US, we can talk you through a quick adjustment of the truss rod due to a change in climate after it leaves our humidified facility. 
  3. All items are fully insured in shipping, worldwide. Although issues do happen, we put a strong emphasis on fantastic shipping practices to make sure your new instrument gets to you safe and sound anytime you order from Ish Guitars.  If your item is damaged in shipping, please contact us so we can assist. 
  4. You can return an item for any reason (simply just don’t like it, etc) 5 days from receipt of the item. This does not apply to international orders nor to instruments with custom modifications completed by our tech team per the customer's request (pickup change, strap button install, etc.) You will need to pay the return shipping cost and actual outgoing shipping cost (even if “free shipping” is offered). A 3% restocking fee applies ONLY if paid by credit card in our showroom, over the phone, on IshGuitars.com, or with PayPal on any platform. A 5% restocking fee applies with Klarna orders and a 10% restocking fee applies with Affirm orders.  You will NOT be charged a restocking fee if paid with cash, check, bank wire, or credit card via Reverb Payments. The restocking fee is only to cover our credit card processing fees which our processor does not refund to us in the case of a return, even if the order is cancelled same day. If an item is not returned in the condition which it was sent due to personal use, we will charge a restocking fee according to the amount of blemishes, as determined by Ish Guitars staff.
  5. Please use all original packaging materials to return an item. Before shipping your return, please conduct a 'shake test' to make sure there is no movement of the instrument or case inside the box. If an item is not returned in the condition in which it was originally sent due to shipping damage from inadequate packaging, we will charge a restocking fee according to the amount of blemishes as determined by Ish Guitars staff. 
  6. Store credit or exchange credit can be redeemed 1 time towards a new item purchase, making that item a final sale.
  7. All returns MUST receive an RMA number (contact us at team@ish.guitars or 315-447-3243) to be returned. If you ship an item back to us and do not get an RMA number prior, we will charge a 10% restocking fee for any return. Returns will be processed and a refund issued within 3 business days of us receiving the instrument at our warehouse. This is to allow time for the guitar to acclimate to room temperature as well as to be re-inspected by our tech team. 
  8. Order cancellations which have not yet shipped are still subject to all of the same restocking fees as outlined in line item 4.  Again, this is only to cover processing fees that do not get refunded to us by our payment processors.
  9. We do not offer an additional warranty outside of the 5 day return period, but we are happy to help you work with the manufacturer or your local tech to solve any issues. Call us! Used items do not carry a warranty of materials or workmanship since they are second hand.
  10. All trades are final, we cannot reverse a trade.

      Available only at PRS Signature Dealers like Ish Guitars - the PRS J-MOD 100 is one of the most sensational amps to ever be created. We personally played through a J-MOD at the 2017 NAMM show and it was incredible. It seemed to have a little bit of everything; some Fender, some Marshall, some Vox, and lots of Dumble. 

      PRS SIGNATURE DEALER - FREE CONUS SHIPPING - NO TAX OUTSIDE NY

      Like John Mayer's PRS Super Eagle guitar, the J-MOD has a sound all of its own, yet with the perfect amount of classic inspiration. The head is $5990 and the 2x12 Cabinet made to match is $1090. We can separate if needed. 

      Open and Expressive

      “I think amplifiers are such interesting, complex animals. The J-MOD 100 is the result of a lot of searching...what is my sound? What are the elements of all these amps I own that should be chosen to go together in one amp and have this really distinct voice? What we ended up with is a really open and expressive amplifier that I feel is a real evolution and a step forward in guitar amps." – John Mayer

      No compromise amp designed with John Mayer.

      The J-MOD 100 amplifier was intimately designed by Paul Reed SmithDoug Sewell, and John Mayer to not only handle Mayer’s live work with Dead & Company, but to also move seamlessly into recording and performing Mayer’s solo work. With a thoughtful control platform, impeccable build, and high-quality components, the J-MOD 100 is a fully-realized, high-end piece of audio gear for players who want the purest and most expressive musical experience.

      Thoughtful control platform and feature selection.

      The J-MOD 100 amplifier is a single channel amp featuring a switchable gain stage and effects loop. The amp’s tone stack features a beautiful, spread out tone that is at once huge and clear. When the gain stage is kicked in, the amp gets rich in harmonics and delivers a bit more bite. The versatility provided by this setup allows the J-MOD 100 to deliver a huge variety of sounds whether using singlecoils or humbuckers.

      Additional tone-sculpting features include a bright switch, which adds more high-end to your tone, and a presence control that boosts the high-end in the power amp section of the amplifier, giving you a livelier, more complex tone. There is no reverb built into the J-MOD 100, but an effects loop was requested by Mayer for his reverb tanks. The amp’s effects loop (and gain boost) is controlled by the footswitch, so players can use any reverb or effects unit desired with this amp.

      Elegant and robust construction.

      The J-MOD 100 amp features five separate boards, all with over-sized traces for tonal integrity. Each board is dedicated to a particular part of the circuit: preamp section, power section, front panel controls, bias jacks, and the effects loop. Not only is this an elegant way to build with fewer long wires extending across a larger board, it is also a more robust way to build as there is not a single, large board that needs to flex during transport. The amp is hand-wired at PRS in Maryland, USA with a truly artistic level of craftsmanship. The J-MOD 100 also features a “laydown-style” power transformer for build integrity.

      High-quality components.

      The J-MOD 100 pairs hand-crafted construction with top-of-the-line components, including a Cinemag output transformer and high-end capacitors in the preamp section. The result is authentic vintage tone with rich harmonics that sit at the player’s fingertips for a thoroughly expressive and transparent musical experience.

      Built with serviceability in mind.

      Mains fuse, B+ fuse, and bias adjustment jacks are accessible on the back panel of the amp, so changes and adjustments can be made without needing to open up the amplifier. In addition, the amp will accept many different power tubes types, including EL34, 6CA7, KT77 (with re-bias).
