Title: Tube effects loop
Post by: 67polara on August 17, 2010, 09:32:09 am

I am sure this has been discussed before.  I want to build the Tweed Overdrive Special, but I would like a buffered effects loop.  I am looking at the Dumblator circuit and I have a few questions.

1.  What tube is being used?  AX, AU, AT???

2.  What voltage on plates?

3   What do the 2 switches do?  

4.  Will it change the tone any?

Thanks for all your help

Tony

Did I place this in the right area?  Never mind I will figure it out myself.

Some of the D_mble cloners use this IronSounds effects loop and give it favorable reviews.

Relatively inexpensive and compact:
