Modifications For Guitar Amplifiers

Modifications to production amplifiers are quite common. Modifications can be done to change the tonal characteristic, gain, or fundamental functions of an amplifier such as adjustable bias.We mainly get involved with functional mods such as but not exhaustive to:

-Adjustable bias control

-Master volume and PPIMV

-Adding extra speaker outputs

-Upgrading cables

Compromise and trade off

Not all mods are created equally even, and there can be a trade off with a simple mod against a  loss.  A classic example is that a tone boost can cause a tone cut elsewhere. 

A Master Volume modification can change the tone of the sound from quiet to loud.

The good, the bad, and not often spoken- the ugly

If you are going to research about Mods on forums it is very important to understand not only the good, but also any bad also associated. The good elements often outweigh the bad elements however and a compromise is made.

Being Realistic

If a Marshall was made to sound more like a Fender on clean, and more distorted like a Mesa, Marshall would have made it like that.  There is a certain level of respect needed to be given in why amps have their function such as they do, the designers spend much time trying different drives, distortions, EQ to get it right for their signature sound. 

Amplifier Clone Mods

We have many, many enquiries where people have purchased clone amps and for some reason believe they are needing to be modded.  Honestly, if you’re going down this line, just buy an original.  Simply upgrading every part in the long run will not add any value, it will still be sold as a clone regardless of it being “hand wired” with the finest orange drop capacitors.
