krispn Posted November 1, 2023 Share Posted November 1, 2023 (edited) Selling my Colourbox as I now have other transformer based goodness in my signal chain. This has had a full once over from JHS due to a noise issue (which turned out to be caused by a cheap Amazon 9v wall wart) so is as up to date as you can get - they basically dropped in a brand new circuit with all the most up to date revisions so it’s as new. It’s been home use only but has been on a pedal board and used as a DI/recording preamp for some projects. JHS did a great video showing the CB as a preamp for a host of instruments and it’s a great tool for the home studio. There are two transformers, one on each output, so if you want some heft on you instruments you find it within this box. I have a couple of passive LBA transformers which I’m using on my board now instead of this so it’s surplus. Don’t fix it in the box get it right first time with this Neve based preamp! Full spec here: https://www.jhspedals.info/colour-box-v2 Might consider some p/x. Quite fancy a Squier Paranormal bass Edited February 28 by krispn Typo’s 3 Quote Link to comment Share on other sites More sharing options...
krispn Posted February 28 Author Share Posted February 28 (edited) Might take a pedal in trade plus cash either to me of from me. A Caveman pre amp might catch my eye or something like MBD dirt pedal Drop me pm if interested in talking p/x and/or trades.

krispn Posted March 30 Author Share Posted March 30 (edited) Seem something which has caught my eye. £350 over the holiday weekend - if the other unit I’m eyeing sells we’re back up to the asking price. Edited May 4 by krispn Quote Link to comment Share on other sites More sharing options...
krispn Posted May 4 Author Share Posted May 4 Janek has just done a massive DI/preamp shoot out and you can hear this compared to other similar units. ***Spoiler alert below*** Janek is taking the coloubox on tour! 4 Quote Link to comment Share on other sites More sharing options...
LukeFRC Posted May 4 Share Posted May 4 I think that it’s one of the nicest sounding in that shootout - Simone sounded great too. Quote Link to comment Share on other sites More sharing options...
krispn Posted May 4 Author Share Posted May 4 Aye I think I could hear the weight of the transformer compared to the pre amp before it. Only I have now theee LBA passive transformers on my board and my main tube preamp it would get my main preamp slot. It’s a top notch eq and sounds big just by being in the signal chain!

krispn Posted May 6 Author Share Posted May 6 (edited) Just been messing about on this again as I was asked some questions via dm and thought it might be useful to those who were looking… All eq info at the bottom of this post. Hope folks find this useful! First the treble sounds class. 2kHz at its lowest and in about the 2-4kHz range adds nice top without clack for us bassists. It can add air as the freq goes up but honestly for the bass in about 0700-1000 is where it’s at for me. Lo/Hi gain. The pedal can be clean or varying levels of low gain and break up right to the famed ‘Revolution’ guitar sound - that classic console type break up. If you have a lower output bass the hi switch can really add some oomph and width to the sound in conjunction with the Step control. I’ve a HB jazz with I think ‘original jazz’ Bart’s and this elevates that bass - it sounds great but the added sonic weight is undeniable! It competes with my Flea jazz and going back and forth I can simply flick the lo gain mode for the flea (it’s hotter output) and go high gain on the HB and it balances them nicely- all analogue and can be dialled in in seconds. Into the efx return/power amp. I used this into the fx return on my Fender rumble and it slays. Into a cab ir to FOH and you have those transformers and a magical sounding eq to have a very over-achieving eq/di. I still bring it as a back up but my main pre/di has been bombproof hence the sale. The HPF This starts at 160hz. Some initial thoughts and documentation said 60Hz but it’s 160. Don’t panic though as you can use the Pultec trick of engaging the Hpf at its lowest range (160hz) but boost the bass frequencies below or at 160hz and there’s no loss of low end. The mid control has a massive range too so you can still dial in addition mids freqs to suit your room/mix. See below for the range on the eq’s frequencies: Frequencies controlled by EQ Shift Knobs: Treble Shift - 2kHz to 30kHz – CCW lowers the center Freq, CW raises the center Freq. Middle Shift - 150Hz to 2.4kHz – CCW lowers the center Freq, CW raises the center Freq. Bass Shift - 20Hz to 440Hz – CCW lowers the center Freq, CW raises the center Freq. The Hi-Pass section is enabled by the toggle switch below the Hi-Pass knob. Just flip it up to engage the Hi-Pass knob. The HPF is a 2nd order 6dB per octave highpass filter. The -3dB cutoff freq (the frequency at which the filter starts to act) can be adjusted from 160Hz to 650Hz.
