Tech-in Mind Electronics - Do-In Instruments - AGP-1 Analog Guitar Effects Processor, 2009
"This strange gem is an all analog signal path multi-Fx with 13 all analog effect modules plus 2 internal effects with digital control of all parameters. ...
This was the brainchild of a Hong Kong startup called Tech-in-Mind Electronics in 2009. The unit is called the AGP-1 (analog guitar processor 1).
The effect modules (my guesses as to what the circuit mimics):
Compressor/Noisegate (sounds like a Ross or MXR)
Phaser (sounds like a Phase 90)
Hot Distortion (Rat maybe)
Chorus (analog chorus, not a chorus connoisseur, so no clue what it is like)
Tremolo (solid state trem)
Fuzz (don’t know what flavor, but it is fuzzy)
Acoustic Simulator (sucks as an acoustic simulator, fun as a sound maker)
Metal Distortion (thicker and more high harmonics than Hot Distortion)
Octaver (tracks and sounds like a Boss octaver pedal)
Auto-wah (70’s flavored envelop filter sound)
Flanger (analog flanger, smooth and nice)
Overdrive (sounds like a Tube Screamer to me)
Delay/Echo/Reverb (The delay is gorgeous! It is as tasty as any analog delay that I have had (Memory Man and DOD). Not a reverb at all, but it is a legit bucket brigade analog delay. Enough delay time to get dotted 8th and quarter note delays depending on tempo. No idea what the millisecond time is.)
It also has two internal effects:
7-Band EQ (reasonably flexible)
Amp Sim (I compared this to a Tech 21 SansAmp classic and it sounded identical to a specific setting that was clean and warm)
Additional features:
Mixer with several inputs (see photos)
Metronome
Tuner (not the greatest, but works in a pinch. Headstock tuners put it to shame.)
The AGP-1 came along at the height of the DIY pedal building movement, and I would guess that many of the circuits that were popular among builders at the time were used for the modules.
The 10 modules can be moved around into different order in the 10 internal slots. It is a fussy business moving them around as each module has something like 30 pins on them that need to line up with the sockets in the main device.
...
Oh, and it has an RS-232 jack intended for firmware updates. It was rather dated in 2009. It is comical now! The company is long gone, so no firmware updates."
A retro 80s version of the Devi Ever console?
