[sdiy] reverb schematics

[bootsy at LABYRINTH.NET.AU]

Hi Andy

I have heard of people having good results with fairly standard 
opamps as drivers and pickups.... particularly good results seem to 
be had when the driver coil is in the feedback loop of the driver 
opamp...

I remember Tony Allgood posted a message in 1999 describing 
successful use of 5534 opamps in a similar way to the concept in the 
above website.

Search the S-DIY achives at http://www.buchi.de/sdiy/

Also, by tweaking the filter values (caps etc) in for the driver and 
pickup opamp circuits you can tailor the response of the reverb to 
your liking :)

If you use low noise opamps and good grounding technique you should 
have a very good sounding and quiet unit (unlike a lot that are 
around...)

I am planning to try something similar in the next week or so - will 
keep everyone posted on the outcome...

Good Luck!
