I first noticed the hiss this weekend at a gig.

Hi ABM users: I've just had a similar problem to Dagrev occur: when there is nothing plugged in to the amp it is silent with the master volume up; plug anything in and it hisses, even when the input gain is right down (and master up). I've tried different cables, basses and the problem remains; and these same cables and basses are fine into another amp. The hiss is right at the 2.6kH frequency, so it can be pretty much eliminated by taking that eq fader down to the mid point, but I need to get it fixed. The amp was serviced three months ago when it had a new preamp tube and a thorough pot clean. Any insight into what this might be? I can easily take it back to the tech who serviced it, but would welcome any thoughts first.

Another vote for a v3 Rumble 500 combo. Just the right height to sit on too.

I've just put a new rig together - ABM EVO lll and Monaco - our band is a four piece v/g/b/d covers band playing mostly pubs and small festivals. I gave it its first run out yesterday - absolutely superb. Plus lightweight, fits in car easily etc. I've just put a review of the Monaco on the Monaco thread if you want to know more about the cab.

First gig report: I purchased a Monaco last week and gave it its first run out at an outdoor gig yesterday. My first impressions are that this cab is superb. The sound of each note from low E to high on the G string is even and balanced and speaks clearly, just like the bass does when practicing using headphones. Setting the amp's eq to flat the speaker sounds a little bland but once eq is set to taste then the sound really comes alive, it is full, rich, clear and present. The ABM is a perfect match with its seven band eq; after a few adjustments on the fly I had a really pleasing sound, with a touch of drive and compression to complement; in melodic, sensitive passages it felt like my technique, the string and the speaker were working as one as if it was an acoustic instrument; and in fast, loud passages with the drummer moving around the low toms muddying the sound, now each note spoke clearly through the mush. My only gripe is that there aren't rubber feet on the cab - easily solved - I can see the corner protectors getting pretty scratched up quite quickly and the cab needs a mat at home to protect the wooden floor from getting marked. So overall this is a wonderful cab, yesterday was the clearest and most even sound I've ever had on stage. I'm really excited to be taking this forward with me on my musical journey as I think it will help me become a better bass player.

my set arrived today - they work fine, but look a little fragile so I'll just have to be extra careful.

thanks for the heads up on this

I did an experiment with my Minmax this afternoon - I unscrewed the fan and took it out, powered up the amp on my desk with the fan running away from the chassis. The same noisy fan was virtually silent, so it is the casing that creates the noise. I need to find a way to make a 'silent' mounting.
