"Tubey" preamp/DI without actual tubes

[ra0ulduke]

Because I'll be performing more often in the future, I'm currently rethinking my setup and want to follow a no-nonsense approach. I own several tube preamps/DIs, but they're too sensitive for my liking for touring. I've recently heard stories of tubes failing mid-set, and I'd rather not experience that. So, I'd be interested to know what your favorite tube-sounding DI/preamp is, one that doesn't actually use tubes. Price isn't the primary concern right now. I'm looking forward to your replies!

I've got a Caveman BP1 Compact, which sounds great to me. It has it's own baked in sound (basically enhanced low-mids) that I like, so you would have to be happy with that. I think that it sounds great, it's got a top quality DI and sound engineers seem to like it.

I've actually had my eye on that device for quite some time.

What about the Origin Effects line up. There’s a few.

Ahem... How about a Behringer BDI21 for £15 UK Posted?

Cheap bit of Backup Insurance

Nano Cortex. Get your preamps in there. Sell them all. Which will pay for the Nano Cortex. I am fully aware that there are subtleties which would be lost as different instruments interact with different front ends in different ways. But as soon as the Guitarmageddon kicks in, those subtleties will disappear anyway.

I personally don't like these units. Thank you anyway.

That is absolutely fair enough I wish you well with you search.

If you are looking for a top end preamp in a pedal format then look no further than the Jad Freer Capo.

I have a Sadowsky pre amp which is excellent. So effective it almost makes my Cort sound like a Sadowsky.

I’m a bit of a Tech21 fanboy, so I’m probably biased. They’ve been making preamps for bass and guitars for absolutely ages and I’ve never had a day’s issue with any of their products over the decades and their customer support is exemplary in my experience (they’re even BC members). I currently use a VTDI which gives me a wide array of Ampeg type tones, but other tones are available and it’s been a staple of my pedalboard since I bought it (so long ago I can’t remember, but around 10 years ago). Others swear by the BDDI and the Paradriver. Their products are definitely worth a look.

Same here, Tech21 gear sounds great, is super reliable, and as a bonus sound people seem to love it too.

Have you ever had an issue with the lack of a ground lift on the DI?

Nope, never had any issue at all. Every sound engineer who has used the DI has always loved it. 

 

I know that it is transformer balanced, which the spec claims will 'avoid any hum/noise issues and eliminates the need for an external D.I./Line Driver' and that there is an amp ground lift (that to be fair, I thought was the same thing).

It’s a lovely preamp but I wouldn’t say it has a “tubey” sound at all? It’s very hifi IME

Yeah - it may be a language / translation thing but it felt weird to me that a product like this wouldn't have a ground lift. As you say - it mentions an "amp ground lift" but I had always understood that the ground lift function on a DI disconnects one of the pins on the XLR, whereas "amp ground lift" suggests it's doing something to the jack out instead. 

 

Sorry for derailing the thread!

I've never really thought of it as 'hifi' and it seems to have a nice warm articulate sound, which you might think of as being 'tubey'. I am always using it in front of a hybrid amp on gigs, so it is difficult to say really. I have been told that it does sound great out front, when the DI is taken from the Caveman.

The DI does work very well when used on gigs, but beyond that I'm afraid that this is all a bit above my paygrade!

I'm also a Tech 21 fan and use the BDDI v2 and have been super happy with it. I'd love to try the VTDI just to hear the difference as well.

Whenever we have preamp threads more people recommend the Tech 21 than anything else. Thus said I really like my Genzler Magellan pre because it has two very different "flavours" (foot switchable), a HPF, mute switch, and really powerful EQ settings. Not sure if it sounds like "tubes", but through the IEMs yesterday it sounded awesome (albeit I also add a Keeley compressor as well).
