Alas, it seems my supply of cheap Chinese stuff to review has dried-up completely. If fact, all the cheap Chinese stuff has dried-up - just look at eBay. Oh well, I don't need another "Phas" pedal anyway. A number of the products have disappeared from Amazon as well, but the pedals are still in stock, and they're even cheaper now.
First, I am bound to state that I received this item at no cost for review. Having gotten that out of the way …
I always wanted to try a wireless transmitter, so when lotmusic offered me this one for review, naturally I accepted. The design is simple. An internal battery in each piece is charged by USB, Y-cable provided. A mechanical on/off switch conserves power.
My verdict on active tone controls for a guitar is that they are not worth it. There is already plenty of treble, and not enough bass that boosting it will make much difference. If you want to try an active control on a guitar, try an onboard distortion instead.
But the Artec EXP tone control is a funny thing. In the middle, it gives a flat clean boost. Turn it forward, and you get a high/low boost, or what amounts to a mid-scoop. Turn it back, and it gives a mid-boost. Sounds interesting, so I decided to try one.
These were my first two tries at a 325 bass. Both are plywood over pine hollow-bodies. The one on the left - #1 - used an experimental neck mounting that I didn't like. The one on the right - #2 - suffered a router mishap. I took all the good parts and built the solid-body, and both of these bodies spent years on the scrap heap.
