Mod Kits

On this page I have listed all of the kit's that I have available along with the pricing. Electronics parts are available from many sources. The advantage of buying a kit from me is you get all the parts you need to do one of my modifications in one complete kit. The parts come packed individually in plastic bags, marked with the part number, making it easy to identify which parts are which. My prices are reasonable and I ship by USPS Priority Mail, which is the most cost effective shipping method for small packages with great service (US addresses only).

note: Sorry for the increase in shipping, USPS just bumped their prices >16%. It's still a good deal compared to the other shippers.

VT50 Stage I mod kit
The Stage I kit includes all of the parts needed to remove the clipping diodes and replace them with a ground reference resistor, modify the tone stack, add cathode by-pass caps, add small capacitor to 3rd stage plate load resistor and modify the Presence control to work on both channels. The results of these mods are like taking a heavy blanket off the front of the amp. Much better clarity & reduced muddiness. The overall tone is not changed too much, maybe a little reduced bottom end (which helps with the clarity), but the overall sound is much more open.

Attitude Mod Kit
This kit includes all the parts you need to add the Attitude mod, which involves installing a potentiometer into the negative feedback circuit to allow you to adjust the amount of nfb fed to the amp. Adjusting this really changes the whole attitude of the amp, hence the name. You can adjust from the stock setting to one that is much more agrresive, or anywhere in between.

VT50 LED mod kit
The Nomad/BelAir/VT50 amps are great channel switching amps, but how do you know which channel is activated? When you're playing on stage and you're getting ready to start a song, how can you be sure which channel you're on? I used to have to hit a chord and listen to the amp, then stomp on the channel footswitch to change channels and strike the chord again to verify I was on the right channel. What a pain in the neck!!!! Simplify things, add some LED's to the front panel so you can instantly see which channel is activated. This kit comes as a harness you install following the instructions for this mod on the VT50 page.

VT50 Master Volume mod kit
This is a post phase inverter type of MV, which retains the tone of the amp much better as you turn it down. This helps to get the lead channel cooking a little better while keeping the overall volume down. And it also helps get the clean channel warmed up and keep the volume down.This is one of the most useful of the VT50 mods, I use it so much I can't imagine not having it.Highly recommended.

VT50 Stage II mod kit
The Stage II mod involves replacing almost all resistors and capacitors in the lead channel of the amp and results in much smoother distortion and greatly enhanced clarity and definition. Each note of a chord can be clearly and disctinctly heard without the fuzzy muddiness of the stock amp. Allows you to use the Soak beyond 3, all the way to dimed if wanted. I typically play my Nomad with the Soak set at 6, no muddiness, just great classic rock distortion and plenty of it! Besides enhanced smoothness of the distortion this mod revoices the channel, inspired by vintage British amps, the tweed on the outside of the amp doesn't really fit the character of a Stage II modified amp. Great classic rock, blues rock, even approaching 80's metal type tones available.
Includes parts for the Attitude mod.
No step by step instructions for this mod, the kit comes with a schematic for you to work from. Intended for more advanced skill level as the amount of work involved in much more intense than with the Stage I mods.
