I have been using an EBS Valve Drive for at least 10 years. Found it quite useful but always felt the overdrive distortion came in too fiercely when the gain was turned up. So the effect was either completely dry or too overdriven (for my taste). I want valve warmth rather than overdrive. Eventually, I got round to trying some replacement ECC83 (12AX7) valves, but generally these were even more aggressive than the stock valve. Finally, I tried an ECC82 valve. These are not regarded as drop in substitutes for ECC83, but will not cause any harm. The ECC82 is much lower gain. The ECC82 is exactly what I am looking for! Very warm sound well before breaking into overdrive. The pedal runs very quietly with regard to background noise, and it is much easier to match level between pedal on and pedal off. Very pleased, and can’t wait to get back to some UK gigs to try it in anger.
