I´ve been messing with the tone stack a little. Didn´t try it on my dr-103 yet, (just on a fender 1watt little amp), but this is what I found:

First of all, this seemed to be a tweaked original laney supergroup amp tonestack. The treble side is more or less the same, (bright cap a little bit lower), and a 100k treble pot instead the original 250k. The bass cap network would have like infinite resistance and mid control goes all the way to ground, (like mid pot at zero I guess). I´ve been messing with the tone stack calculator comparing the laney tonestack vs an aproximation of the pedal tonestack with all controls at noon, (I used a linear pot instead of a logarithmic for the wizard treble pot) and this is what I found:

The scoop curve is the pedal tonestack and the other is the original laney. As we can see, the scoop frequency on the wizard doubles the original one, (800kz vs 2000khz), leaving a lot of what I consider ugly "paper board" mid frequencies.

If we upgrade the "mid" cap to 22n, (like on the original laney tonestack), the scoop frequency goes down a little, cutting some of the ugly low mids, and getting a more pleasant tone on my 1watt amp.

We can go further with this, (up to 56n cap), where where we can even match the original mid frequency, but the scoop goes like 12 dbs deeper...

Anyway, I upgraded the bass cap up to 470n and noticed no bass increasing... Looking at the tone stack calculator, the 22n cap gave a boost around 60/90 hz, so maybe the circuit just don´t have more bass to show.

I will check it out tomorrow on my big amp, and see what I get.
