I had a T-Rex Tremster some years ago, it was a very good sounding tremolo. I sold it when I bought Boss TR-2, but I have to say that the TR-2 lacked the organic feel of the T-Rex.
I have volume-modded my TR-2, so thatīs no issue any more.
Are there any mods I can do to get my TR-2 sounding a bit better??
Iīve googled and didnīt find anything concrete except the volume mod.

| I've seen some mods that play with R31 and R19 (try lowering them). Never seen a "full" mod published for it. |

| You could try and remove C7 to give it more sparkle... |

Yes, that is what he do, I read an article by him about it.
He also put a volume pot, a double pot like the ones on MT-2. so the TR-2 could be used as a booster (with depth at zero),
I will change most of the electrolytes to metal film and listen to the difference.

Did change most of the electrolytes and polyesther caps yesterday, and removed C7.
Well, the sound is a little more open and there is more high end sizzle (C 7 probably).
All in all I would say that itīs not worth the job, TR-2 is good sounding without changing a lot of caps.
The important thing is to change the resistor (10K) that handles the volume, I use 5.5K, on the older TR-2īs.

Just wanted to bump this rather than start a superfluous thread...
Has anyone tried the Monte Allums or the Analogman TR-2 mods? They both seems more or less the same, save for the Monte having an external 'boost' control and the Analogman having an interior trimpot 'boost'. |

Possible mods:
The rate is controlled by R31: change it to something between 22k-10k
R19 controls the waveform: change it to something between 2.2K-6.8K

haha what a coincidence, I'm picking up a TR-2 tomorrow for $15 and thought I'd check here for some mods and here is this thread 
Anyone have any info on the keeley Depth/Volume knob? I don't mean to potentially derail the thread but does anyone have any info on any other TR-2 mods besides whatever the OP is looking for? |

Some developments.
I added a Rate LED that displays the Pulse Rate whether the pedal is On or Bypassed. This can be done by connecting the + leg of the LED - with resistor, to LUG 3 - I think it was, or 1, of the Rate pot, the other end of the LED to ground.
I also removed R19 - 10k I think it was, and added a 10k pot. I remember reading somewhere that R19 would fix the volume drop - though mine is a newer version, but cctism posted that R19 effects the wave shape...I found that a 10k pot actually boosts the pedal. I have it wired so the pot fully CCwise is 10k, fully Clockwise increases volume...

Decreasing R19 should have a boosting effect too. The gain of IC3b is set to attenuate -R27/R19 = -1.5/10. Therefore, if you use a smaller value for R19 you increase the gain.
In the newer TR-2, boss uses R9 to adjust the mixing volume. They have replaced R9 with a trim potentiometer that is fixed with hot glue. |

Does anybody know when exactly the circuit change of the TR-2 (to remedy the volume loss) took place?
I read before that it was in "late 2006", but does anyone know from which serial one can be sure to have a "fixed" TR-2?
Should we start a "TR-2" versions thread like that one for the CS-3? |
