The Toolbox is, more or less, and as far as I can see it, a direct copy of the Broughton Messenger Jr.
Disclaimer:
I'm not really a fan of cloning pedals that are still in production. Making a pedal based on another, but adding your own idea to it is one thing, doing a 1:1 clone is another. When the cloned pedal is not in production any more, I do think it's fair game for anyone who can wield a soldering iron with the required precision.
With Broughton, this is a bit of a hairy situation, since they tend to move pedals to the archive, which means they are not in production any more, but sometimes, they bring one of them back in small batches, which also means they are not entirely out of production. However, at the time I was talking to Disssa, not knowing that he had the Toolbox in his portfolio, I asked him about a pedal that has a parametric mid EQ, HPF, LPF and DI out in a small form factor - because IMHO, that is the perfect end of chain pedal for a small setup. He then offered to build a Toolbox for me, and said that it's a copy of the Messenger Jr, only the switch that toggles the foot switch is on the inside.
I researched the Messenger Jr (and I had tried to get one for a while now) and at the time I ordered the Toolbox from Disssa, to my knowledge, the last drop of these has been in early 2024, with no drop in 2025 and none planned in the foreseeable future. I concluded that the Studio One, which does essentially the same thing has taken over that spot in the Broughton catalog and that the Messenger Jr seems to be retired for good, so I went with the pedal that I can have right now instead of the pedal that might or might not come some time in the future, but a possible drop is not even planned.
Here's my take on the Studio One vs. the Toolbox:
The main differences in my personal use case sum up as such:
-The Toolbox has a shelving lows EQ with a corner frequency of 80Hz, where the Studio One has 40Hz. I like 80 a lot more.
-The Toolbox has a weird behavior with the Foot Switch, because you can choose whether it mutes the signal or only takes the EQ and LPF out, leaving the gain and HPF on at all times. This makes it a bit difficult to balance the on/off state when you're using EQ for boost, because the gain knob is the only way to control the output on the 1/4" out. I don't mind any of that, because I use it always on.
-The Studio One has that red gain knob that is supposed to be a special kind of boost that brings some magic. To my ear, it's a normal gain knob that will give off some nasty, unwanted fizzle if you turn it up too high. I can't find the magic in there, so for me personally, there's no magic there
-The Toolbox takes up less space on a board, and since I use it on a Nano, that is a huge bonus.
Other than that, it's a very nice 'boring' pedal. It does a ton of utility, acting as a cab sim with the filters, and giving you some channel strip like EQ that works super efficient without much coloration. It is super straight and linear and every knob does exactly what it says with no surprises. There's no magic here, but an insane amount of utility. Tubedrve into Toolbox is a great combo, because it covers the whole lot. You get your EQ, your filters, your signal shaping and your magic tone sweetening and a DI out from two 1590 shaped boxes.
