There is no depth control on the Vibrato, just an on/off footswitch (itself a study of 1960s charm - check the 'more pictures' link below) and a speed control, which is PERFECTLY calibrated, unlike many amps - just a great sweep from a nice moody, slow vibrato up to a great, characterful speedy one. And a nice sine wave quality to it, not choppy or harsh in any way. The amp has a really 'gainy' character to it, and is surprisingly loud through the original MSP 8" speaker. If you have a vintage guitar with fading pickups, this has tons of gain to still let that pickup drive the amp into beautiful low-wattage distortion. It would also make a great harp amp, due to the gain. The volume knob acts more as a 'clean/dirty' control, as when a guitar is plugged in, even with the amp's volume turned right down you can still hear the guitar (nice and clean) bif the guitar's volume is wound up. A higher value potentiometer in the volume control would 'fix' this, but I really like it, and the pot is definitely original, so I have left it as is. Output valves are 2 x 6GW8 in push-pull, giving about 8 delicious watts. These are a triode and pentode in the same envelope, sort of a 1/2 12AX7 and an EL84 in the one valve. The other valve is a 12AU7, which would use one of its triode 'halves' for the tremolo. Once again, the Electravox/Vadis blurring of brands occurs with this amp. Just check out THE BEST WEBSITE ON AUSTRALIAN VINTAGE AMPS and see the Vadis equivalent - it's exactly the same! Both great brands, and finally slowly getting the recognition they deserve.
