The reason I got this was the fact that the Supro Delay has an expression pedal input. My idea was that I could control the delay oscillation by using the expression pedal.
You can imagine that I was surprised to not get any kind of oscillation at all out of the box. Double checked the (online…) manual - that’s right, it should oscillate by cranking the feedback knob.
Ok, so, turns out there are trim pots inside (it’s an analog delay after all) and by adjusting the pot labeled R40 I was able to “extend” the range of the feedback pot. I think this is very useful to know for people who are getting this, because the oscillation sound itself can be half the reason you get this pedal in the first place, am I right? The feedback setting out of the box was very modest. Glad I figured out whats under the hood.
So another point I want to share (and the reason for the title), is that the way the repeats are going to ramp up will depend on the tone knob as well. Set it to lower, darker sounding repeats and the oscillation will kick in much much faster. Turn it clockwise - you may wait for the feedback to build quite a while, if it happens at all.
I read a lot of comments of the repeats having hiss. It’s true, but it is also quite mild and to me personally ads extra charm. Also I think that depends on the level amount. After a certain point the level passes unity and that’s where the hiss can be more apparent. Overall I think it sounds great. If you want squeaky clean sounding delay lines you’re not the target audience here, for sure.
So yeah, it’s like a little instrument all by itself, you will need to learn it’s quirks. I like it so far.
Overall, I think it’s a worthy purchase at a discounted price. The type of enclosure used and the presentation of the pedal (I like paper manuals) doesn’t really give me a premium feel you would expect at the original price. Glad to have it nonetheless.
