TAD Class-A Converter Tri-Tone

Easy to fit and work fine but don't really reduce the overall amp volume by much, so don't fit their purpose for me and my amp (Rivera Chubster) and in fact sounded worse than the stock tubes. I'm looking to get more gain for leads so will use a pedal instead.

Don't let me put you off if you have an amp with no master volume though, as they should help.

I was hoping to return not for a refund but Thomann say I can't as tubes aren't covered by their refund policy - a bit harsh as this isn't exactly tube replacement.
