COMP-1 | Bass Player (September 2003) | Demeter Amplification

demeteramps.com

The Demeter Compulator is a straightforward compressor that impresses with its detailed and transparent sound. With a design inspired by the iconic LA-2A, it offers easy-to-use controls and is adaptable to various bass setups. Its solid-state circuitry and rugged build make it reliable for gigs and recordings. The Compulator excels in delivering sweet, well-mannered tones that enhance your music without being overbearing. However, the lack of an LED to indicate compression activity might be a minor inconvenience. Overall, it's a first-class compressor that many bassists will appreciate for its subtle yet significant contributions to their sound.

Not For Me

After considerable deliberation & research in the optical compressor market, I gave this a whirl, primarily w/ a view to using in conjunction w/ an acoustic. It is VERY subtle tool & did not change or help fatten my acoustic tone as i had hoped ( the LR Baggs Session DI did!). I was also intrigued how it might work w/ my electric but again it was once again way too subtle for my taste so I reverted back to a modded BOSS CS3 (see my review). This pedal is a bit of a pain to power in that it requires an additional adaptor to a standard BOSS plug to operate. To install a battery you need to take the whole casing off & there is a tricky trim pot at the side of the unit to adjust input gain.

Not for me but I sold it on to a bass playing friend who says it is working out well for him so... :)

I thik your problem is that the 'fattening' from classic optos isnot about the LDR detection circuit but about the gain staging surrounding it! some old optos are not fat at all while others are thick as hell, particularly tube ones... the opto thing is a studio thing, its about the more relaxed curves on the time cosntants, when someone uses a tube opto to thicken things in a mix its more for the tubes in the signal path, particularly the make-up amplifier after the compressor, the actual compression is typically used pretty subtley. This is a question of mistmatched expectations because people don't really explain the components of famous circuits and their effect on source material and instead make things like "opto compressor" into marketing buzzwords :-( not your fault.... you might prefer the Cali76 that gets near an 1176 Fet compressor in a pedal, the 1176 is super 'grabby' and definitely adds more girth from the other parts of the signal path than a lot of other solid state compressors.... also remember that if 'fatten' involves big low end, ALL comrpessors tend to reduce lows when working hard un;less the makeup am compensates for this through a flattering design. I hope this has been informative.
