I know these Legendary Series pedal are supposed to be preamps used in an effects loop. This review is based off of running in front of an amp like most pedals are intended.

This pedal is attempting to sound like a JCM 800 tone but it comes up way too short. At best it is a lousy Boss pedal tonal look a like. This unit sounds so bad through any amp. AMT has many good sounding pedals and this is not one of them.

- The AMT Legend Amp Series guitar pedals provide excellent dynamics, nuances, and characteristics similar to that of tube driven amplifiers.
- Tube-like range of volume control provides great sound density, playability, and power when playing at full volume and also in conjunction with your guitars volume knob.
- TRUE BYPASS. The preamps of the Legend Amp Series pedals use passive true bypass circuitry, therefore no loss of guitar signal is noticed in your pedal chain. Similar to if no pedal was there at all when bypassed.
- Features high level of output signal (+10dB in extreme position of Level knob) corresponds to the output levels similar of tube preamps. Thus, you have adjustable signal level allowing to hook up your preamp AND direct input of a power amplifier.
- Controls include LEVEL, GAIN, LOW, MID, and HIGH.
- TWO signal outputs: DIRECT AMPLIFIER OUT for guitar amplifier use and CAB SIMULATION OUT for mixer, or studio use.
- Power saving mode. When the speaker simulation output jack is not in use, the pedal automatically switches to power saving mode. Current consumption (from 9V power unit) is less than 6mÀ (in power saving mode it drops to 4mÀ).


This pedal is easy to use with only five control knobs. The tone from this pedal is just terrible! I wouldn't play this pedal if you paid me.

There is nothing to this pedal as it has the basic EQ controls with high mids and lows. The levels and gain are the other standard controls as you see on most distortion boxes.

There is no need of a manual as no preparation will get you able to make this box sound good.


This pedal is better suited to stay with AMT then for it to make an appearance on anyone's pedal board. I hate the way this thing sounds. It tries to be a Marshall JCM 800. It doesn't really matter which guitar or amp you play with it, it is going to sound bad. If you get this pedal free somewhere and you have to try it then I would use a humbucker style guitar because with single coils it sounds its worst. It is very thin and the tone is brittle. Unlike most AMT pedals this one sounds exactly like a pedal and nothing like an amp.


This pedal is garbage and you would be better off never owning it. It doesn't sound anything like a Marshall JCM 800. I'm sure there will be people who say it is amazing and great but take it from me a guy who has owned several JCM 800 from various sounds nothing like one.

I would not recommend this pedal to anyone. Save up a few more bucks and buy a used real JCM 800. The price is around $130 new which is in the high end for AMT
