Verified PurchaseThe replacement board resurrected my JCM2000 DSL. The amp sounds better now. The tone is glorious. I appreciate the design upgrades in this board over the original unit. Most importantly, I am deeply impressed by the updates Stewart sent during the production and shipping process. His dedication to customers is first-class.
Thank you for taking the time to so the review. Your nice comments are really appreciated.
Verified PurchaseHighly recommended
Each came with a written test report and also checked for noise.
Thank you for the feedback. We invested in our own custom equipment because standard AVO type testers could not check for noisy valves.
Verified PurchaseMuch better materials from the OEM boards, and sounds just as good, but a lot quieter!
Hey thanks for the feedback. Looks like our efforts going well beyond just making a copy paid off 🙂
