ossyrocks Posted August 23, 2024 Author Posted August 23, 2024 Erm, I can't really believe this myself, but I'm probably picking up a 400RB MK-I this evening from a member here. There have been crazy coincidences surrounding this, and I still won't believe it until it's in my hands. I'll keep you posted. And yes, I know, I'm hopeless. Rob 1 Quote
ossyrocks Posted August 23, 2024 Author Posted August 23, 2024 Oh dear. This has to stop. I'm done now, unless someone comes up with an 800RB...... Back in February @The fasting showman listed a 400RB MKI. It was one here for a while, a couple of months, and at that time, they weren't on my radar. This was before I had heard @shug with his amp at Ribble Valley Jazz & Blues Festival, and I knew I had to try one. Anyway, the amp got withdrawn before it sold. Very late last night I contacted Martin @The fasting showman, to see if he would reconsider his decision to withdraw the amp and sell it to me. "Perhaps" was the answer, but no postage. Then we realised he and his family were coming to stay in a cottage 12 minutes from my house, today!. The heavens aligned, and we met up this evening and the deal was done. We had a bit of a chinwag, much of which was in praise of these amps. @cetera I think Martin is still kicking himself over selling you his 800RB. So here we are, a MKI, MKII and a MKIII 400RB. I'm so chuffed I can't tell you. Rob 6 1 Quote
Lozz196 Posted August 23, 2024 Posted August 23, 2024 You’re gonna have one for every day of the week soon Rob (and possibly two for Sunday). 2 Quote
The fasting showman Posted August 23, 2024 Posted August 23, 2024 Nice to meet you Rob, doubtless I'll kick myself for selling it...I'm currently in the where are they now file so glad it'll get used in anger. My 700rb will suffice. As I was saying, the Backline 600 shares a lot of circuitry and parts with the mk3 and 4, because of their price point they're often neglected and treated as a utility item. If you get a good one they're great amps, often dirt cheap. 1 Quote

bremen Posted September 3, 2024 Posted September 3, 2024 There's suddenly so much online interest in these that the CIA are going to start making enquiries... Looking at the schematic of the 400 preamp (because I'm nosey and I've read this month's Viz), it looks like "flat" eq is with bass and treble at 12 o clock, and the mids both at max. Am I right?

They don't sound like that to me. Everything at noon seems to be where flat is, when compared with other amps. 2 1 Quote
msb Posted September 3, 2024 Posted September 3, 2024 I found the RB series to have their own voice. And starting with everything at noon was a wonderful place to begin. Probably one of the easiest amps to dial in. 2 Quote
bremen Posted September 3, 2024 Posted September 3, 2024 'flat' always sounds very middle-y on a bass. I think Bob knew that and realised that no-one would want to boost the mids, hence the options are 'flat' or 'cut the mids'. 1 Quote

Yeah, I find the same with my 400RB Though I guess what sounds 'flat' can be quite subjective & can depend on choice of cab, room acoustics etc... Here's the settings that I perceive as 'flat'-ish, at least to my cloth ears with a couple of 12" Vanderkleys. 2 Quote

We could, and perhaps should, do a whole thread on eq and gain settings on the RB series of amps. I’m a big fan of higher boost settings, around 2 o’clock is where I’m at, and I’m not playing rock, it’s blues on a P bass with flats. Rob 4 Quote
Minininjarob Posted Thursday at 09:40 Posted Thursday at 09:40 (edited) Just to dredge this up from the archives, I got my 400rb from ossyrocks and eventually I managed to get a GK cx210 cab to go with it for a decent price. I also refreshed the 400rb, respraying the cover plate black, touching up the white decals that had scratched off and popping it into a SKB flight case. Oh my it sounds glorious. Even into a 8ohm cab it has plenty of volume as far as I can tell. I need another cx210 cab to make a 4x10 4ohm stack now. Total outlay on GK gear now £610. 400rb, cx210 and MB112mk2. So so cheap!

ossyrocks Posted Thursday at 20:17 Author Posted Thursday at 20:17 An 800RB arrived here today! 4 Quote
BassmanPaul Posted Thursday at 20:41 Posted Thursday at 20:41 I bought an 800RB via Ebay that needed servicing. What arrived was a pile of junk. Blown power amp, chassis parts missing. Naturally the seller was no longer on the site so I was stuck. I decided that all I could salvage was the pre-amp. I intend to drive one of my other power amps with it. One day I'll get round to doing the conversion work! LOL Quote

bremen Posted 19 hours ago Posted 19 hours ago Yes. I had a look. Was tempted by a power supply/power amp board but I have food and drugs to buy first. 1 Quote

I just got another 700rb power amp module for £30 and a preamp for £15. Repairers can't seem to be bothered with fixing them so it's a good backup. I've used my old 700rb for 10 years so they work for me, small enough and more than loud enough so if I can keep it working myself, all good. Thanks for the heads up Edited 15 hours ago by The fasting showman Poor syntax! 1 Quote
