Small FX loop for clones

[heisthl]

I'm not sure - I think it has been referenced by dogears and it definitely is kinder to a 12AX7.

'Also the 10k/1.5k string on the cathode should be raised to 27k/1.8k.'

Is this actual Dumbleator info? Or a member's tweak?

It is from at least one real deal box.

Was this real deal box running a 12ax7?

Yes a 12AX7, using the alternate values you should get about 25 to 30v on the cathode (depending on your supply) and also should notice more clarity in the loop as well as increased headroom. It is very easy to clip the signal with the stock (1K5 / 10K) values.

It does and it doesn't - the amp has to sound good or the loop won't do anything for it. The loop really doesn't distort much even on 10s with no external FX plugged in. What the loop does let you do is run more treble through the OD and smooth it back down which allows another variation in OD sound complexity. On the clean side a similiar effect takes place - that extra gain stage can give a little more sustain and rounder tone. Unless you have a really crappy effects unit I would doubt you ever need the bright switches.

once you CORRECT the dator, the reverse is true @ treble! Mine freakin SMOKES..

Anyone selling a ready-made version of this?
