New Tube For My Blackstart HT-Dual

By: on 13 January 2022
Bought this tube as a replacement for my TAD ECC83WA and I am not disappointed this new tube brought my Blackstar HT-Dual back to life, no more microphonic issues (loss of power and other odd noises) the pedal operates now like it was brand new, awesome tone. Fantastic service too, ordering was nice and easy and the tube was carefully packaged and expressed shipped to me.
