I am thinking of purchasing a JJ Tesla preamp valve for my new amp the Vox VR30, it only uses one valve, as it's a hybrid, tube/solidstate amp.
I have found one on ebay for around £10, but I need to know how good they actually are!
Have any of you guys got any clips of a JJ valve in action? and if you own a JJ valve are they actually a lot better than an average valve?
I hear they are well worth the money.
cheers,
Ben.
