Roll Cage



Fragile, unprotected sliders inches from a footswitch is a recipe disaster; especially on a dark stage. A simple roll cage setup allows access to the sliders while protecting from falling mics, inaccurate feet, and wandering pedals. Going rate is $30 installed and DIY kits are available for $20 by emailing us.

Always use the right power supply...



Surprisingly this pedal was still function despite the significant damage done to the circuit board and part of the power supply circuit.

Surface Mount ICs



Upgrading opamps for better sound quality is very common request. The commonly used (and dirt cheap) JRC4558 may be popular for Tubescreamers but is not be ideal for circuits when you want the most transparent sound. Burr-Brown and other companies make excellent chips to retain sonic fidelity. Above is a photo of their surface mount chip which was used to upgrade the signal path in an EHX Holier Grail.

Monster Face "Organ"
