rubis Posted August 9, 2019 Share Posted August 9, 2019 Treated myself to a new amp, my first valve bass amp, and very pleased I am too. I noticed it while on holiday, on Gear4music's website and they had 7 in stock at £375! I have wanted one of these for a while and missed out (last time we were on holiday!) when Kenny's Music were discounting them heavily, so I thought 'what the hell' It will be for home practice and recording, and will hopefully match up nicely with my home built P bass I have another project in mind...…..I am going to have a go at making a B15 style cab to match it, the early double baffle one, like this one which is a modern reproduction made by a company in the USA called FlipTops It's actually marketed as an extension cab, and as such doesn't have the flip top lid, which I wasn't interested in anyway, so it will be a removable back with the fabled double baffle design at the front. I have had a quick doodle with it plugged straight into an Audient interface and it sounded great, it should be lush with the 2 Notes Ampeg cab sim added. Very pleased, I have been missing out on the valve sound for years! 6 Quote Link to comment Share on other sites More sharing options...
JapanAxe Posted August 9, 2019 Share Posted August 9, 2019 I often gig the 50W version - most satisfying! Makes a great recording pre-amp too, with the built-in 8-ohm dummy load. 1 Quote Link to comment Share on other sites More sharing options...

Cat Burrito Posted August 10, 2019 Share Posted August 10, 2019 I like the custom cab idea. I use my PF50t a lot and it's great in the studio so I would imagine the PF20t would be no different. 1 Quote Link to comment Share on other sites More sharing options...
Beer of the Bass Posted August 10, 2019 Share Posted August 10, 2019 Should be a nice little amp for recording purposes and lower volume stuff! Regarding the cab, as far as I gather the double baffle cabs function like a more conventional ported cab with the same tuning would (though I've never seen a clear answer on what the port tuning was). So there could well be a simpler route to the same result. 1 Quote Link to comment Share on other sites More sharing options...
RedVee Posted August 10, 2019 Share Posted August 10, 2019 I use a PF-20T for home recording and it gives me great results using the transformer out directly in my audio interface. The PF-20T is likened to the Ampeg B-15 and the PF-50T is likened to the Ampeg SVT- VR. Quote Link to comment Share on other sites More sharing options...

Hi RedVee this is more or less the sound I'm aiming for, hopefully with the right kind of cab and/or cab sim I can get close Looking forward to hours of aimless fiddling !

Thanks Beer of the Bass Whilst I was on holiday I had time enough on my hands to look for info into the fabled double baffle cabs, and you are tight, there is a surprising lack of clear information on the dimensions, I couldn't really find any complete plans, for example, as you can for other cabs, but I did find a drawing for the front baffle with the port slots in, and enough other dimensions and information to have a crack at it. I have a sheet of 3/4" plywood, which has been lying around for years, so there's not going to be much cost involved. baffle.pdfbaffle.pdf Quote Link to comment Share on other sites More sharing options...
Chimike Posted August 11, 2019 Share Posted August 11, 2019 There is, or was, a very detailed drawing of the Ampeg Heritage B15 cab, put up by the guy who built the repro cabs. Try google . If no luck, PM me, and I'll hunt out my copy. mike. Quote Link to comment Share on other sites More sharing options...
