Turn that workhorse PCB amp into a sleeper hot rod. In most cases you don’t need to ship your whole amp, just mail in the chassis. How it works: Add this item and checkout. We’ll send you our address. You pack and mail your amp to us, we do our thing and when its done we’ll send an invoice for the return shipping. We’ll mail it back on receipt.
These mods use the existing stock circuit board and topology and do not cut or damage any traces. We make changes to components throughout both the signal path and power supply to completely re-imagine the circuit and change the amp’s performance.
More details:
Signal path components replaced with higher quality parts and modified values
Optimized gain structure for clarity, tone and response
Excellent overdrive tones. Thin, grainy and buzzy stock overdrive tones are completely transformed.
More balanced EQ between Clean and Drive channels, no more thin drive channel, your tone controls can be left on same settings for switching clean and OD!
Fullness without flub, tightened bass response without thinning out the punch
Preamp triode stages re-baised to provide excellent touch sensitivity and smooth transition into overdrive
Inter-stage coupling caps and filtering circuits improved for focused and dynamic sound
Improved volume control sweep with expanded sweet spots.
If your amp needs repair service too, we can take care of that in addition to the mods via our standard service rate: 90/hr labor + parts.
“Standard maintenance” Power supply filter capacitor replacement and re-bias is $150
If you have a different model amp you’d like modded, please reach out! I am always expanding my repertoire and many amps are good candidates for mods.
