Mallory M150 series

The Mallory 150M series signal caps are our top choice for affordable, great sounding signal caps. Beautiful, lush & sparkly Fender cleans; smooth, round high end; rich, creamy breakup when pushed. They impart a sweet “vintage Fender” style tone, and are a major improvement over stock silverface caps. M150 caps (with outside foil marked, of course) are our shop standards.

These caps are recommended as upgrades for silverface Fender amps, or replacements for blackface amps if the original blue 'molded' caps are missing.  We do not at this time offer signal cap kits for tweed or brownface amps.  Signal caps for tweed and brownface amps need to be ordered a la carte - as singles, and Jupiters are recommended for 'closest to original' sounding replacements in the Tweed, Brownface, and Blackface amps.

If you want to add the TWEED PREAMP mod to the first channel of your two channel amp, just add the 'SUB TWEED PREAMP MOD' to your order for $5!  This gives you the parts (caps, resistors and instructions) to install the tweed preamp INSTEAD of the stock components for your first channel!  Instructions for adding 'reverb in both channels' is also included!  This will be for the 'normal channel' in most two channel amps, and the BASS channel in Bassman amps!
