bassmayhem Posted June 3, 2023 Share Posted June 3, 2023 (edited) I got my Caveman Audio BP1 delivered yesterday, a very basic bass preamp, developed by Steen Skrydstrup in Denmark. Read the tech here: - Hi-Z Cable Input - Transformer-balanced gold-plated Neutrik XLR Wireless Input (on one model) - Transformer-balanced gold-plated Neutrik XLR DI - Transformer-balanced gold-plated Amp Out jack - Adjustable Gain and Level - Switchable audio loop - Transformer-balanced Tuner Output - 9VDC output (50 mA) for powering your tuner - Unique RFI protection and Silent Switching - 10 Year Warranty - Road-ready, zinc-plated steel enclosures Easy to use, two pots: gain and level, two stomp buttons for Mute and activate the Effects loop. I tried it in my home studio yesterday and has just one word to say: Wow! What goes in comes out, just better and more of it. This one will never leave... Well, to say more than Wow, it is truly a remarkable piece of gear. Studio grade at your feet. Harshness disappears, everything is more or less "soft and wooly" but with a clarity over the whole tonal spectrum. My plan is to use this preamp with just a compressor and a tuner, for a high end all analog signal chain. Next week I get the pedalboard delivered, a PedalTrain Metro 20. If I should complain about one thing, it is the 9 Volt outlet to power the tuner. It could have been "beefier" than 50 mA so it could power the compressor too, but that's no big deal. I chose the PB1 over the PB1 Compact, since I wanted a unit with REAL power and not the wall wart. I will add a power supply under the Metro too for any effects pedal to use in the loop. Maybe an envelope too... I got the BP1, my cat got the bubble wrap; both are happy... Edited June 3, 2023 by bassmayhem 11 Quote Link to comment Share on other sites More sharing options...
BassmanPaul Posted June 3, 2023 Share Posted June 3, 2023 Thank you for taking the time and effort to do this review though I'm sure you only did it to please your cat!! 1 Quote Link to comment Share on other sites More sharing options...

Tee Posted June 4, 2023 Share Posted June 4, 2023 Nice. So compressor in the loop for best results? And I guess for recording, DI out straight into your recording interface? Quote Link to comment Share on other sites More sharing options...

Check this impressive flow chart: DI out for recording or PA. Perfect! Edited June 5, 2023 by bassmayhem 2 Quote Link to comment Share on other sites More sharing options...

I have owned the Avalon U5, and have the Jule Amp Monique. Also had the BasSwitch, EBS MB2 and MB3, TwoNotes LeBass, Sadowsky, 3LeafAudio Enabler, Bassics Pro BPA-1, the Goliath etc. The BP1 is a different beast compared to Monique. She is more a pristine valve amp in a small format, that can be a little bit dirty. All the others are "pedals" in comparison. The BP1 is a very clean but powerful piece of gear that just makes the bass sound bigger, better and "beautifuller"... Hence the Wow! Most preamps nowadays induce ugly preamp/input gain distortion and try to convince us they really are SVT's in a small box. Since I don't fancy overdriven SVT tone, but like the pristine clean powerful bass, the BP1 is the right thing for me.

I have a Sonic Farm 2di4 which I think is fantastic and was thinking of getting a Caveman to compliment it. Quote Link to comment Share on other sites More sharing options...
bassmayhem Posted June 5, 2023 Author Share Posted June 5, 2023 I tried the BP1 with my acoustic upright; it sounded very good. No eq tweaking needed, it also felt like it is not so sensitive to feedback with the BP1 "in between". The amp i use is the Genzler Magellan 350 combo with a BA10-3 cab 3 Quote Link to comment Share on other sites More sharing options...

Ive been running- bass into small board with SFX 2 band EQ, compressor, Sonic Farm, then power amp and speakers- lovely sound, with hardly any EQ. The Caveman has been on my radar, but unsure if to spend the money on something that might not make a lot of difference. The bass pre-amp rabbit hole you can go down is massive, if you had the funds 2 Quote Link to comment Share on other sites More sharing options...

Noble meets Monique kinda thing. Edited June 6, 2023 by krispn 2 Quote Link to comment Share on other sites More sharing options...
bassmayhem Posted June 7, 2023 Author Share Posted June 7, 2023 I've noted that the unit has a VERY HIGH output. The LED's in our PA mixer and my audio interface in the home studio flashes red with very low signal sent from the BP1. I am not used to that kind of power...

Brucegill Posted June 21, 2023 Share Posted June 21, 2023 How are you using this with an Amp - Straight into the front, or in the amps FX loop? thanks Quote Link to comment Share on other sites More sharing options...
bassmayhem Posted June 22, 2023 Author Share Posted June 22, 2023 My amps have no loops, so in front. The output level compared to other preamps/DI is very high, but my amps can take that. (Genzler and Vanderkley Spartan...) 1 Quote Link to comment Share on other sites More sharing options...

Robc666 Posted July 23, 2023 Share Posted July 23, 2023 I think the reason the DI output is so hot is because contrary to its name, the DI out is in fact +4 balanced Line Level, and not mic level as on DI boxes. the terminology is a bit confusing especially as the forthcoming BC1 has an XLR labelled Line In (which is balanced +4 line level) and also , just like the the BP1 series, an XLR labelled DI Out - which again , is in fact a balanced +4 line level out. not entirely sure why both the BP1 and BC1’s XLR outs aren’t simply labelled Line Out, because that’s what they are ! 3 Quote Link to comment Share on other sites More sharing options...
E sharp Posted July 23, 2023 Share Posted July 23, 2023 They should do it like I have on my Sonic Farm pre. All options are here 1 Quote Link to comment Share on other sites More sharing options...
Paddy777 Posted October 21, 2023 Share Posted October 21, 2023 I am seriously looking the BP1 compact version of this, I was actually thinking of running another tone shaping preamp like the Goliath light in the effects loop along with the compressor - would that be overkill/unnecessary do you think? I’m not sure if I am looking at it wrong, or if it’s just the lack of EQ options scaring me 😆 Quote Link to comment Share on other sites More sharing options...
krispn Posted October 21, 2023 Share Posted October 21, 2023 (edited) If you want a killer preamp and you want to spend some dough you have to consider the Simone preamp by Jule Amps. If you can find one to demo you’ll appreciate the quality it brings and it’s versatility. Tubes, great eq, drive and boost. It’s a very complete package (but on fx loop) and I think it surpasses the Noble in terms of what it can do. If it’s a Neve style preamp you’re after, something transformer based, then a Hudson Broadcast or JHS Colourbox v.2 would be a great option. Both do the preamp colour but the JHS has added eq options and transformers on both the di out and the 1/4” signal path. - you can hear what it does - but again no fx loop. I’m selling a Colourbox v.2 btw 😉 Edited October 21, 2023 by krispn Quote Link to comment Share on other sites More sharing options...

For a killer preamp I would suggest something featuring a high voltage current transformer, then opening up said preamp while plugged in and then start groping the innards electronics until you hit jackpot. If it's not yourself you are planning to kill though anything heavy enough with a good aim to the head of your victim should do.

You can surely add some flavour to your liking in the loop. The new compressor is NOT in the loop; it is post BP1. 1 Quote Link to comment Share on other sites More sharing options...

Alanbass Posted November 30, 2023 Share Posted November 30, 2023 Paddy 777 - did your Caveman Audio Compact arrive? What do you think of it for playing through your amp direct? Cheers. Quote Link to comment Share on other sites More sharing options...
