EA TRem, yet again

[aaronkessman]

Figured since i had access to a digital camera for once, i'd take a few pics of my crazy EA trem build in a cigarette tin. the circuit is on busboard, I'll try to get a layout up tomorrow.

I can't call it a 'box', it's too cute, and round for that.
 Very Nice !!

looks very cool

Wow, cool style I wish I had room for stuff like that, but one of my goals is always "keep it compact" :mrgreen:

Yup, pedal-building rules

thanks for the comments guys.. ..
in terms of size, this box is just slightly wider than a 1590BB and a little bit shorter. being round, there is a bit of wasted space. the board could fit into something much smaller.

nice one~
to be honest, i think the ea trem sounds as good/better than the vibrato built into my 70's twin reverb.. definately a rewarding circuit..

alright, finally got around to doing a computer layout. Sorry it's so shoddy, i did it quickly in Paint. It's small and a little blurry, but you should be able to make it out ok.

you can make it more compact by moving those first two busses on the left down to the bottom row. but it's pretty tight as it is as you can see in the pics.

alright, that didnt work. here it is:

Do you have the values for the numbered caps and resisters? From the looks of it I could finally breadboard that with your diagram and see what I think (I know I want one, just want to hear it, I'll be getting a blues jr without trem and could use it for a few tunes in our band). Thanks.

Clever Build Aaron, and it won't take up a lot of space on your pedal board,

The part values can be found on GGG's EA Trem page, specifically the original schematic which is here:

look at the mods page - I used them. Not that it matters to the layout.

Thanks! Appreciate it.
