    So I currently own a Yamaha PB-1 and I have an AMP (Amplified Music Products) SL-1 on it's way to me.

    Both have parametric EQ's, crossovers and a lot of other bells. Can't wait to have the showdown with the two.

    Any of you try both? Any opinions?

    I own the SL-1 and its very similar to SWR products. If you like the sound of SWR you will certainly enjoy the SL-1 pre amp. I have no first hand experience with the Yamaha Pre.

    I had the Yamaha Pb-1 many years ago. From what I recall it's a solid preamp with fast transients and a very very solid tone. I don't know what the High Pass is set at but I remember some extreme low frequencies that would really piston my speakers. So perhaps keep an eye on how much bass boost you use. I would highly recommend this pre-amp overall.

    It's been many years since, but I've owned both. The Yamaha was a nice pre, but it was clean and clear and back then I was looking for processed rock tones. I liked the AMP much better... it was also clean, but with multiple semi-parametric bands plus other EQ features I had lots of fun.

    The weird thing about the AMP is that it's 1-1/3 rack spaces, but if you have two free rack spaces then you're good to go.

    I thought I would like the AMP more, but so far, I like the Yamaha. It's just a bit more punchy and modern sounding. I've played with the EQ on each a bit. Oh, the Yam is hotter as well (higher output).

    The real test will be at a live performance, in the mix....

    Go with whichever works better for you (well, duh ;)). Cool rig!

    Thanks Ken! Maybe I can get you to play it at a gig soon (since we are local).

    In putting in more time with them, I'm leaning towards the Yamaha. I really didn't see this coming.

    The Yamaha is far hotter (drives my amp better) and has more of a cutting tone. I can get a similar tone with the AMP, but it loses just a little off the top and bottom and has a little less clarity.

    If you like a slightly more vintage tone and want more versatility, the AMP is the way to go.

    If you want an amp with a HOT signal output and want more zing (modern tone), the Yam is the way to go. It also has a few more options that I like (level control on DI, effects sends and returns, grounding switches for the main amp and DI, etc).

    I never A/B'd these two units directly. I'm basing my preference on the fact that I preferred my solid state preamps to have fancy EQ, so of course the SL-1 hung around longer.

    I'd love to check out your rig and revisit those preamps. I definitely want to see your band regardless. Unfortunately I have a conflict with your 1/25 gig, but we can hook up sometime soon after that I hope!
