Tube Amplifier Modifications
Unlock the hidden potential of your existing amplifier with targeted modifications like bias adjustment, tone-stack tweaks, capacitor upgrades, and more.
Tube Amplifier Modifications
Sometimes a great amplifier just needs a little refinement. Maybe the tone controls feel stiff and narrow, maybe you want a brighter clean headroom, or maybe you've always wanted a master volume on your non-master amp. 1337 Sound's modification service is all about dialing in your specific sound.
Common modifications include cathode-bypass capacitor changes for added gain and warmth, presence and resonance circuit additions, negative-feedback reduction for a more organic feel, bright-cap adjustments, adding an effects loop, or full channel voicing changes. Every modification is reversible on request, and we document exactly what was changed so your amp's history is preserved.
