Trace Elf in good working condition. Tiny but mighty. An ideal home practice, spare or gigging head. I’ve used one a number of times with PA support and even in smaller venues on its lonesome. Comes with carry bag and mains lead. If my other amp I have up for sale sells first, I’ll be keeping this. Pics to follow but it looks just like a Trace Elliot Elf bass head. Postage mainland UK £10 or collect from Blackburn Lancs.

For sale, excellent condition. TWA Krytical Mass. Brassmaster style Fuzz with more than most! Huge sounding with plenty on tap. More tonal variations than other Brassmaster fuzzes in the market. Huge low end and gain on tap, all important clean blend and various 2 lpf's and a hpf for tones, choice of 3 position mids. Edge to add in some top end, bias to get those sputtering synth like sounds, phase inverter to take some low end out if gets too boomy, this can go loud! Web schpiel: Prepare for meltdown with the TWA KM-01 Krytical Mass®! Based on the coveted Maestro Bass Brassmaster, Krytical Mass® was born from exhaustive critical analysis into the inner workings of that Holy Grail device and the few noble attempts that have been made to clone it. Krytical Mass® spits out fat, formidable fuzz with a pronounced octave up as well as a more subtle octave down and a scorching, filter-like sweep on sustained notes. Muted notes will “kill” the fuzz with almost gate-like precision, yielding a super-tight, synth-like pulse that is simply addictive to play. Where other replicas tend to be harsh and sterile sounding, Krytical Mass® is able to capture the aggressive yet warm & organic edge of the original Brassmaster using a unique complement of EQ and voltage manipulation controls. One of the great mysteries of the Brassmaster is its unmarked transformer and how it was wound. Analysis suggests that this component may have actually been wired with negative polarity, so Krytical Mass® includes a switch to toggle between positive & negative phase wirings for additional tonal options. Another unique feature of Krytical Mass® is the ability to adjust the symmetry of the transformer to taste, accentuating either 2nd order harmonics for more lows or higher-order harmonics for more complex waveform content. Also on board are selectable HP, LP and BP filters with adjustable midrange to fine-tune Krytical Mass® to your particular tonal tastes. Fuzz sensitivity of Krytical Mass® can also be controlled via external EXP pedal for dynamic manipulation of the fuzz to create synth-like drive swells and other interesting effects.

@Beedster my apologies! It sold offsite some time ago and I forgot to remove it here 🤦‍♂️ Now using a Xlson which I’m very happy with - excellent on pizz, and surprisingly good on arco!
