What we can modify and customize.

Modifying a historical instrument can be considered a sacrilege. Every amplifier, pedal or anyway an electronic effect has been conceived by its designer to play in that precise way, with all its merits or defects. Our code of ethics respects the approach followed by our colleagues and therefore we do not modify pedals with the presumption to improve them, but upon request we can customize the sound by acting on the circuit according to our way of designing. As a guideline, below are some classic tools where we have already made some mods.

Boss SD1 Super Overdrive
Boss SD1 Super Overdrive BOSS

A timeless classic. We propose greater sustain and brighter timbre; among the operations performed it is included replacing the 4558 with another op-amp with better dynamic characteristics, especially for high gain.


Boss MD2 Mega Distortion
Boss MD2 Mega Distortion BOSS

Taming this small Japanese devil is not so easy; our customers often refer us problems due to the manageability of the very high gain featured by the Mega Distortion. We propose changes on the action of the three gain stages and on the pre-emphasis network.


Ibanez DE7 Delay/Echo
Ibanez DE7 Delay/Echo IBANEZ

We propose a personalized opening tone and presence in “Echo”mode (original repetitions are too dark), light smoothing in the “Delay” mode to get more realistic repetitions and less “fotocopy” feeling.

Ibanez TK999 Tube King
Ibanez TK999 Tube King IBANEZ

The supply voltage of this classic pedal is 9Vdc provided with its original linear power supply. We propose a modification of the supply filter so that it can be used with modern switching power supplies also in daisy-chain way without hearing annoying whistling. We also propose a tone modify that improve the characteristics of the overdrive responce.

Marshall Bluesbreaker
Marshall Bluesbreaker MARSHALL

The Blueskbreaker produced in the 90’s is definitely one of the best overdrive created by Marshall. We propose an optimization by increasing the gain and the maximum output level, since for low gain settings it may be lower than the bypass level, even with the Volume pot set to the maximum.

Vox V830 Distortion Booster
Vox V830 Distortion Booster VOX

We propose the changing of the low frequency response, tone control optimization, tone customization with action on pre-emphasis stage.
