Would love to hear your review of that ABM! I’ve been tempted for sure. The reduced prices on the UK built stuff especially. The Interstellar ABM speaks to meJust Ordered a demo ABM 300 from Sweetwater for $499... They're having a huge sale on new and demo Ashdown products. And they have the new RMs in stock.

I've had multiple ABN variations and they've all been killer. 12band was my first, then a shavo which is just the abm 600 with two VU and an ABM600. I sold the 600 after I moved from a house to a loft and I've just been waiting for the right time to grab a 300. It'll go on my abm410 and I can't wait to get it. I'm currently running my Little Bastard 30 UK build and for those that know, they're pretty magical. That I'm more or less using for it's power section with my Boss GX100. I use 4CM and a few of my dirty patches bring in the tube pre blending with the distortion/fuzz from the MultiFX.Would love to hear your review of that ABM! I’ve been tempted for sure.

The ABM is so versatile and the AB power hits so much harder than any class D I've played. It nails all genres for me from metal and rock to neo soul and jazz.
A lot of people I see in YouTube reviews talk about the tube pre being for drive but Mr Gooday has stated it's there to add harmonic content to the tone and sweeten it up, I find it in the 9-11 O'Clock range. That AB slam is so so good. Maybe ABM stands for A BASS MASSACREThat's what pulls me to em so much. I love using the tube grit, but man, if you switch it off. The punch and attack is unreal. Just blows me away!

Should work great with Bag End S15* variety of cabs as they are Really efficient.It arrived a while ago. The mystery amp is a CTM-30. It It's one of the MBT/non-choke coil models.

I've been playing many different basses through it and OH MY! It sounds wonderful. So much more of all the goodness of my other Ashdowns, but so much more and with the tubey goodness!
I've been using it so far with my Duke LeJeune/TB110 cabs for a sweet sounding mini stack.

Playing with the switches, I'm finding I can keep the EQ knobs set and just with the flick of a switch or two and I can go from a basic clean to dirty tone, a thumping bass tone to a jangly modern tone and a mellow vintage tone.
It's not just the honeymoon phase, this amp will be my number one. I will be trying it out with my Rumble 115 and 210 cabs and the 212 Dayton/Seismic cab.
BWAHHH!
It stopped working before I could post this.
Troubleshooting to figure things out!
I'm thinking/hoping it's just a tube issue.
Somewhat remarkably the ABM powered sub which Ashdown only made for 5 minutes one has turned up in NZ
when I bought my Klystrom in 1998 I wanted the Sub as well but none available….
25 years later… sad thing is pick up only though and seller is the other end of Aotearoa.
I have a 1999 ABM 500 with the sub output as well. Is it just a low pass filtered output? I always wondered because it was the mystery jack I never used! LOL
Me too! I'd like to connect any powered sub to it. In fact, I've been wondering what would happen if I ran it into another bass amp. A little bit apprehensive to do that though! LOLyeah I think the powered sub has the level of the low pass filter.
would like to give it a go

Depends on where you set the gainWhen you press the valve drive plus button, is it quiet until you play something, or is it noisy beforehand?
