CHASM REVERB

[soupbone]

here ya go..

This is exactly what i was looking for! I'm gonna have to build me one!and HELL NO it will not be for sale! Awesome job Rob!

[gtangas]

Just finish it... Yeaaaa

I had to temporary replace one of the FETs by an J201... But ok

The off board wiring is consuming but the end result is very very sweet... Thanks Rob

[haveyouseenhim]

Just finish it... Yeaaaa

Holy crap, you are faster than me!  I've been spending too much time on the bike trail. I MUST etch tonight!

[alanp]

I feel so slow... gotta wait for my board to arrive, first. (Then I have to wait more for the courier to bring my parts.)

[gtangas]

Hehe

with all that wires putting this one in the box will be a nice challenge...

i had the parts and a rub a dub that was unboxed so...

[Maik]

Parts ordered

[bluebunny]

Great movie, Rob.  You ever thought of going into pedal-building too?      I've not even boxed up the previous version yet - I wish you'd give us mortals a chance to catch up.  Oh well, need to go buy another brick, I guess...

BTW, John Martyn would have loved your reverb/delay/chorus combo. 

[bluebunny]

Great work as always, Rob. Love the demo, too. (Especially the epic intro. )

I thought it was gonna be a trailer for the next Star Wars movie...     

[Maik]

I was thinking about two reverbs, one long one middle brick.
Any chance to do this with a switch?
That would be a "one size fits all" reverb

[alanp]

From what I understand, two bricks would draw too much current for the 78L05 reg.

My progress so far:

[Govmnt_Lacky]

From what I understand, two bricks would draw too much current for the 78L05 reg.

Could try a LM7805. Good up to 1 amp 

[Jdansti]

If the idea is to switch between two bricks, then just switch the power too. It might pop, but if you're only going to activate the switch between songs, it's not as much of a problem. 

[haveyouseenhim]

Whoa. This thing is great. Such a lush ambient sound. I'm going to destroy my volume pot on my guitar from all of the swells. 

[haveyouseenhim]

On the original reverb you would need the horizontal mount brick, but since it is wired off-board I recommend using a vertical mount with a waffer connector. It makes things a lot easier than soldering directly to the brick's pins.

I'm not done, but I just wanted to hear it. I plan on wiring it with the option of true bypass, hence the 3pdt.

[pedroguese]

Man!!! this reverb sounds good!! congrats you brainiacs!! now I have to try and build this!! its going on my pedalboard!!

[deadastronaut]

cool glad you guys built/like it...

now to add a delay with lfo...

in fact i think i'll bread up merlins small time delay and tinker with an lfo on it..

kind of mini echobase with tails....it'll go nice with this...

[deadastronaut]

  nice one mike...sounds lush....

the TB was a pita, that's why we just dropped it ..

in the end i couldn't imagine myself wanting a dead cut off anyway with this...(maybe on another build)

i did ask ian about his echobase tails/boss 4066 setup , but he said he couldn't guarantee it would be silent still....

so i stuck with the fet solution as it is dead silent. (required)

[samhay]

Nice demo Mike.
I'm pretty sure you sure you should get no wet signal (reverb) bleeding through in tails bypass once the feedback has done its thing - Rob can confirm this I guess.
It might be that FET 1 is not closing properly on bypass. You may want to try another FET and also make sure the gate is pulled to ground when bypassed.
