The Crunch Box has been around for quite a few years now, and has even inspired several clones and knock-offs. So I threw some ideas around the workshop, and came up with a design that expands the flexibility of the original, without an large rise in price.
First Upgrade: 18V Internal Supply
All stock MI drive pedals can be run up to 24V for more headroom, giving more clarity and a tighter bottom end. We know that a lot of our users run our pedals at higher voltage, but are aware of the troubles of running extra adaptors for these pedals. So a feature I am looking to implement in our future designs is the addition of circuitry to double the input voltage of your 9V adaptor/battery to supply 18V to the pedal. This is a great feature that your pedal board will happy with. The pedal sounds bigger, tighter and more responsive at 18V.
Second Upgrade: External Presence Control
The internal presence control was implemented to integrate easier with every user’s amp setup. Some amps are brighter or darker than the ones we use to test, so by dialling in the Presence control you can control the shape of your sound through your setup. By placing it as an external control, you can really pull some great sounds that sit well in a mix, or to have more control with a range of guitars/amps you might use. The interaction with the Tone control is important as dialling in more Presence can cut really well, but also the lows won’t feel as powerful, so use it with that in mind. This greatly increases the versatility of the Crunch Box, but for those who want to rock it old school, just leave the presence at 50% and proceed as normal!
Third Upgrade: Lo/Hi Gain Switch
This switch adds a great amount of tones that will suit many different playing styles. InLo Gain Mode, the Crunch Box really cleans up well with the guitar volume knob and has a glassier tone. It still has a lot of gain (it is a Crunch Box after all!) but there is more string definition and top end than Hi Gain Mode. Hi Gain Mode is the stock Crunch Box amount of gain, so you can still get that “hot-rod” sound as with previous versions.
