Moody Sounds Kit Page Hi guys, just wanted to put out my thoughts and feelings on the Hjärt Müller Bass Drive, a kit I recently built and a pedal I've seen mentioned here a few times, but haven't read a great deal about, except that the few people who have them really enjoy them. As this isn't a builders forum, I'll summarize the build process as pretty easy if you can solder competently, with instructions that were clear and concise with good pictures. The kit comes with everything you need to build the pedal and the parts for a few recommended mods, none of which I've tried yet, so this review is all about the stock pedal so far. So, the sound: This is definitely a Drive pedal, but with the Drive all the way up, it reminds me of a less-dense Big Muff, possibly due to the tone stack (labeled "Klang") being based on the Big Muffs high-pass/low-pass knob. It's very thick, but not in the same way a fuzz compresses things to be thick. The initial attack of your string seems to get through very well, retaining the punch of notes and articulation of quicker runs that maybe a higher-gain device might compress and level out. Throughout the range of the "Klang" knob, the low end is retained and the notes remain full and pleasing. In the upper ranges of "Klang" I heard a slightly lower-treble-frequency version of what the Tronographic Rusty Box can do, with that exaggeration of pick 'clack' that would probably sound really great subtley smashed by a tube amp. This does NOT sound like a Rusty Box in any other way, however, it is simply similar at one extreme of the Klang range. I tested the pedal with a passive bass, with both a Dark Star pickup in the P-position, and a Q-Tuner in the MusicMan position, but I'm going to whip out the old '74 P-bass tonight and give it another whirl. I initially played the pedal through a Beta Lead into a Bergantino 610, but tonight I'll roll the whole shebang through my Yorkville 400 and/or 800 into the Bergantino 215, and listen for any subtle low-end loss. Until then, this is just a preliminary observational on the Hjärt Müller Bass Drive, and I'll update after more tests! PS: It sounds a lot like the YouTube video on the page, surprisingly enough (sometimes YouTube vids are a little misleading).
