Finally I got the Joyo AC Tone pedal that I've been wanting for some time and I had a good go at it.
This all analog pedal is a copy-ish of the Tech21 Liverpool pedal and it's supposed to sound like an AC30 whether plugged directly onto a PA system, a computer, a clean amp or almost anything else.
First impressions: I ordered this from a store here in the UK and it got to me fairly fast for the mere sum of £29.95 including delivery. I opned the parcel to find a black cardboard box with big neo letters that read "PEDAL".LOL .By the way, instructions are very poor and written in pidgin English at best. Useless, really. Fortunately you can find help about what the knobs do all over the internet.
I first plugged it into a Roland keyboard combo. Not bad but there was an annoying ´glitch´happening in the high end when i pushed the guitar hard. Like a distorting overtone.
Uhmmm...
Then I plugged it into a cheapish Marshall Basstate (solidstate) bass amp with a single 12" speaker.

This amp sounded much better and the glitch was gone. I set the amp´s EQ flat and the sound started to resemble a true VOX amp.
First I tried to go for a Brian May overdriven kind of tone. Well, I wasn´t too impressed. There is a lot of gain available but also loads of hiss and noise. Also the pedal sounded constipated and lacking the dynamics of the real thing.
I backed down the gain and character and soething magical happened. I found the tone for this pedal! All of a sudden I found tones that were not only useable but very, very good too.
Creedence swagger? no problem
REM jangly arpeggios? yep
early the Who? Absolutely
Tom Petty crunch? Voilà!
U2´s the Edge´s shimmering tones? Yeah!
Gallagher blues? Granted!
Even some AC-DC tones!!
Some lessons I learnt:
This pedal´s EQ knobs are very effective. A tiny movement either way will transform your sound. Not at all like the typical amp tonestack. More like the parametric EQ at the mixing desk.
Lower gain settings sound more natural and convincing than high gain (this pedal has loads of gain!)
For the money it is a bargain. Everybody who likes the AC tone should have one! A brilliant piece of analog equipment for sure!
