Holy Grail Reverb

[spruce moose]

I've just modded my Holy grail by adding binary switching to unlock some additional presets on the digital chip. Would anyone else be interested in this mod? I could draw up a wiring diagram

It isn't overly difficult..

It involves rewiring the main switch and using a combination of three spdt toggles instead, although with a bit of thought I'd say it's possible to use a rotary switch.

In my original search for mods I came across "Poboy" and Mark Hammer's thread on firebottle, which was pretty helpful.

I'm not too sure if this is already common knowledge in the community..

Heck yes I'm interested.  What kind of new sounds do you get?  Sounds cool!

[johnnyquest]

It turns out there was a thread on freestompboxes all along. I forget that google is crap at finding forum threads. Dirk Hendrix explains it much more in depth than me

Not is to be taken that the thread is on the other forum and cannot be linked here (technically). For those that, for whatever reason, do not visit there Spruce's document is a nice DIY help to be able to do the job.
