Humster - “20th anniversary, limited order production model. It is a high-quality overdrive built with point-to-point coupling of parts.
Based on HUMSTER Ultimate, the circuit is designed to maximise the potential of each part configuration by narrowing down the variable range of "DRIVE" and "TONE". Both guitar and bass provide the best tone, but it especially matches single coil PU guitars and passive type bass.
A drive pedal with a rich midrange and thick tone.”
Their description…I think it’s based on a tube preamp, but as you can see they substitute an IC (of a kind I can’t identify, the numbers have been removed) in a modified tube socket. The rest is point-to-point wired with PIO vintage capacitors.

Sounds warm and vintage, but not a huge amount of headroom, and saturates very quickly. I find the first third of the travel of the gain knob to be where most of the utility is to be found. Tone seems like a semi-tilt….turning CCW rolls off highs but also seems to add low mids to a lesser degree at the extreme. Highs are rolled off in any case, even with the tone fully CW and gain at minimum. There seems to be a gentle low-mid hump in the EQ, and it excels at “thickening” these and getting compressed, providing a vintage tubey tone, but not much beyond that. Looking at their description, that seems to be their objective, narrowing their focus on a quality build and one particular tone. Definitely doesn’t need to be used with a compressor, even a very clean VCA type.
The Wild Stomp goes for the “tubey” vibe as well…with mode footswitch off it’s supposed to give a tube flavour, although this is more subtle, cleaner, and the Bottom control fills out the lows in a far less obvious way. The mode switch adds another gain stage….Bump is the gain control but I find it can get buzzy pretty quickly. Kick-up seems to be a form of contour, determining the proportion of mids feeding into the gain stage. A nice implementation, but doesn’t feel as “organic” or touch sensitive as the Humster. There are a few YouTube demos of the Wild Stomp.
I’ve discussed the ODR-B elsewhere, and there’s a good review on YouTube by The Wetter Bass. It also has a more “vintagey” overall tone and cuts highs even with the treble control at max. It can do low gain quite well but this requires some very gentle adjustment in the first quarter of the gain knob. It’s also quite compressed. However, the strength of this pedal is the useful sweep of the gain, as even when cranked it still sounds good, unlike other low gainers which when pushed hard over-saturate and fart out. You can even get a passable fuzz tone at the extreme. Plus you can tweak the character of the distortion with the onboard EQ.
The Sex Drive has been discussed at length elsewhere. It’s VERY clean and good at providing a hint of hair. Not good for thickening…in fact, almost the opposite of the Humster as it can compress gently, and add a bit of tasteful clipping as well as top end sparkle from the tone control, which really seems more like a presence control. I tend to think of it like a “hi-fi tube” emulator, rather than a vintage tube amp pedal. Not really a dedicated drive, but a “tone polisher”.
The Bass Blaster is even more versatile than the ODR-B….not as compressed, given the internal voltage is boosted to 15V. I think from memory it’s based on a modified tube screamer circuit. It can achieve the highs the ODR-B can’t, plus the gain control sounds good throughout the full range. In particular, it’s probably one of the best at doing low-gain stuff of all the non-“specialist low gain” bass pedals, which probably accounts for its popularity. If you just wanted a single bass overdrive, it’s a pretty good pick. However, I find it still has a modern edge and I can’t completely dial out some of the highs as much as I would like.
Thank you for that. I have added them to my short list (and searches).
