5150 / 6505 Mods

Clarity mod Gives you a more useable clean channel, get rid of some of the hiss on the lead channel and tighten the overall tone to give you more clarity with less saturation. You get a bigger, tighter bottom and better low volume tones. Includes basic bias mod

Bias mod with test points Gives you two bias test points to measure each pair of power tubes with an external bias pot.

Adjustable noise reduction circuit (lead channel) to get rid of a lot more of the hiss.

Solo boost adds foot switchable solo boost level control for a volume boost.

3 channel mod adds a third set of pre and post controls and foot switchable crunch for those looking to have 3 channels with the 5150.

IEC jack mod replaces the hardwired power cord of the 5150 with the IEC style power cord.

This mod includes the external bias pot mod with test points, Clarity mod, custom output transformer, custom choke, and my own extra mods for amazing punch and dynamics. Added EL34/6L6 switching and bias probe test points.

Custom output transformer Installing a Custom output transformer gives the amp a tighter, more defined and articulate tone. It balances out the frequencies so the lows don't fall apart and get muddy and the highs aren't so harsh. It makes the amp more dynamic with a tighter feel. It improves the clarity and definition of what you're playing so everything isn't blurry.

Custom choke The Custom choke beefs up the power supply by improving the power supply filtering which help with noise levels, improves sustain, and helps the amp stay tight and punchy.

Tone shifts For the tone shift mod I am able to boost or cut either the highs, mids, or lows. I can also install two fixed positions for the mid sweep mod or install a compression switch. Multiple tones shifts can be installed for a wider range of tonal options.

Sweep mod Added pot that adjusts where the EQ circuit operates and allows you to dial in thicker low/mid tones or cutting high/mid tones.
