Haven't tried the Meek but I use a Pro Channel all the time and it's very cool on guitar and bass. Vocally, I get great results for other singers, but it's hard to dial in on my own voice. If you get it, change the tubes immediately. Just sent for a Mullard for the preamp section. Hopefully it will be all creamy-like. Very versatile unit, tho the eq section is a little harsh - I figured a tube eq would be smooth, but, well, it's great on guitars and bass. The opto compressor is great, pretty transparent and simple to use. The tube compressor isn't as versatile, but has a little faster attack than the opto and can be useful if patience is employed when dialing in levels. DEFINITELY worth the price, just don't marry it for vocals - may work for you, may not. and TUBES TUBES TUBES.
