MODIFICATION PLATFORMS

JCM800 2203/2204 (early vertical input jacks), JMP/Plexi 1959 style as the preferred choice but reissues are acceptable. JMP/Plexi 1987, JTM45 style can be modded but they have a very small chassis, so they are limited as to what options can be installed. We offer different mods than the above for many of the newer Marshall amps JCM2000, JVM, 2203KK, Vintage Modern, etc. Other brands such as: Bogner, VHT/Fryette, EVH, Traynor, Mesa Boogie, Fender, Soldano, Rivera, Egnater, Diezel, Friedman, Koch, Laney, Orange, Matamp, Electric, Randall, Splawn, Suhr, Steavens, Vox, etc., can be modded within certain limits. We prefer to not work on any kit amplifiers unless we built them due to the amount of rework involved. Solid State amplifiers welcome but keep in mind that the modifications will most likely cost as much as the amp was to purchase. Custom work is also welcomed, we can work within your budget.

TERMS & CONDITIONS FOR MODIFICATIONS

Modifications are to be prepaid before sending in for the work. Your amplifier should be in 100% perfect working order before sending. Any repairs, demodding of existing work, replacement of faulty/worn out parts, re-tubes, etc will be billed at $125.00 per hour plus parts. This will also add to the turn around time of your order. All shipping, duty/customs/brokerage, and/or handling costs are not included in the modification pricing. If your amplifier needs to be re-boxed, a charge of $50.00 will be added. Fortin Amplification is not responsible for damages incurred during the shipping process. Any outstanding charges will be due in full when it is ready to ship back to you. Modification work is warrantied for 1 year from the date of completion noted on the original Fortin Amplification invoice. This warranty is only valid to the original owner who had the work performed. This warranty is non transferrable. Failure to comply with any of the above terms may result in refusal of your amplifier which may be returned to you freight due. Prices are subject to change at any time.

All pricing is in USD currency
