EL34BSTR-MQ El34 Ruby Tubes, Matched Quad Set

I bought these for my Diezel VH4 amp to replace some other tubes I bought locally that never quite had the sound of the original Ruby tubes used by Peter Diezel himself. Was happy to find these on Amazon and now that sound I had from day one is back and have gone back to buy more. Can't beat it for the price alone.

I purchased a quad set of Ruby EL34 type tubes for my guitar amp. They were the best price for "name brand" tubes I could find. When they came in I tested them on my tube tester and they checked great! Put them in my amp and they sounded great! Liked them so much I purchased another set of EL34's for a different amp. The tubes came in and I tested them and found two of the four tubes had high grid leakage and low output. Quickly returned them to Amazon and was shipped another set from the supplier and this set of tubes tested fine and sounded just as good as the first set I purchased! So in conclusion I would recommend buying these tubes but it is always a good idea to test the tubes before putting them into your exspensive tube amplifier and if you don't own a tube checker find a music shop or repair shop that can do this service for you.

I tried these tubes when I just joined a rock cover band and needed to get some fresh tone out of my old Mesa Simul 295 Amp. I've used these tubes now for about 9 months and they still sound great. It doesn't seem to matter if I'm in a clean sound or I've got extreme overdrive crunch wailing, the tone is beautiful.Great purchase!

These tubes sound excellent in my Marshall TSL122...exactly what I needed at the right price....A-1 for sound! Amazon does it again.....great overall purchase.

Purchased for my son as he plays in a band. He said they were great and very happy with them.
