Tone Bone - Triode Version

Posted by Coburne from NYC on May 30, 2007

Outstanding product for the money. Hassle free and easily reversible "amp customising" for the masses. These little beauties seem to be a pro musicians secret studio weapon - great for playing at home too.

Does the same thing as the THD product, with more saturated tone for far less cash.

Get the THD

I have tried both the Ruby and THD. Get the THD yellow jacket. It sounds a lot better. Plus, it isn't just an adapter, so you don't blow out as many tubes.

Putting a set of 4 in an old Sovtek 100H was a good decision. Sometimes I do have probs with feedback, but it's such a sweet feedback that I am actually learning how to use it...

Decent product, works as described. Build quality could be better - the center pin in one of the Tone Bones broke off the first time I used it which made pin alignment a pain

Adapter pins too long for Fender sockets

Posted by Please help from Pomona, CA on Jan 18, 2003

Adapter pins too long; don't seat against tube sockets in Fenders with 6l6's; tubes shake and vibrate then go microphonic... adapter pins become loose, no idea whether problem is tube or adapter.
