Subway+ Bass DI-Preamp II

The + DI-preamp arrived today, and it is definitely a keeper! I already own a D-800+, so the feature set is very familiar. This pedal will be primarily paired with my GR powered 110 cabinet for lower-volume situations, and will get its first night out on Monday on a piano/bass duo gig in NYC.

I am also thinking that this would be a great pre for use with an IEM system.

IEM use was certainly one of the considerations.
 
Nearly impossible to get one in Europe :confused:
Understood, and sorry for this.

Yes, for the moment they are out of stock, but another shipment is headed out shortly. It depends on the European dealers ordering enough to meet the demand, and I this case the demand was much higher than they expected.
 
So I did it, I went 18V.
Yes as has been stated several times, running at 9V is perfectly fine. I did get an 18V adapter for free so I went there. Yes 9V is fine, but I perceive a slight difference (at least I am telling myself I hear a difference). No really, I hear a little more headroom or more space before the harmonic texture kicks in. A little more turning up of the gain and or boost.

I do like how the boost switched on without turning up the boost knob add a little something extra. That was doing that before adding the 18V.

Anyway it's a little something more with the 18V. Probably more noticeable in the bedroom than anyone on a gig would hear. It might be felt more by the player than heard by anyone else.

Still, I like it 😊

Anyone else have an option to share on it?
 
Andy claims 18v vs 9v is very subtle BUT first he made it 18v capable and I am of the type to be let's say more comfortable knowing it was at its supposed technical best even if I only imagined it sounded subtlety better but I wouldn't A/B in case I was wrong🙂
18V is primarily necessary in order to drive very high line level signals into low sensitivity pro audio power amps (like +10dBu).

So it is gear situational to insure proper operation with any Amp you may encounter: another example of you never leaving a rock unturned in design

So 9v is fine unless you encounter a low sensitiviyy Pro Amp in which you could easily switch to 18v supply and tone cork sniffing doesn't apply🙂

But I still tell myself my Stingray Special sounds better in that they used 18v Active Preamp over if it was just 9v🙂

Correct. There may be an occasional super-high output bass that can benefit from >9V, but not many IME.
 
I've played mine at 9, 12, and 18 volts and cannot tell a difference with my basses. That said, I simply keep a an 18 volt power supply with it. That way I figure if I or someone else need it at a rehearsal or performance (it's my gig saver back-up), I'm well covered for anything. I used mine with headphones Friday to rehearse some songs for a bluegrass and country gig Saturday. It is a handy piece of gear.

Saturday's gig was with the D-350 and an Eden EX110 to blend well with an all acoustic instrument mix. It was a smaller venue private party and I had already worked out some starting point settings if I needed to go with the DI-Pre through the PA. However, the D-350 and small Eden cab worked perfectly to give my electric bass a nice URB kind of feel and sound.

For larger venues the SW112 works brilliantly for blending with an acoustic group. And anytime you need to go through a PA, the new DI-Pre is versatile enough to support any style of music IME. It's all about having the right tool for the job.

I’ll have to A/B mine, 9V to 18V to see what I think I’m hearing 😐

It won’t be blind, unless I can get the cat to make the switch.

“Now how does it sound?”

🤣
If it sounds better to you at 18 volts, in your specific case it might be adding something.

I just run mine at 18 volts and figure I've got the max capability of the box on tap for any use case that might present itself.
