Compact wonderbox

Nikokaoja, 29.12.2018
This is a very flexible comp (not editable thought) + dirt box + nice shaping options included. You really cannot beat this price/performance for all the goodies that come in this stomp box. Excellent little bass helper!

The almost perfect pre amp!

Fabi-Bass, 10.07.2018
When I saw the SpectraDrive, my first thought was WOW, everything I've ever imagined from a PreAmp for the bass in a box!
I usually use the SpectraComp, because I like to have a multibandcompressor on which I can really adjust everything I want. And I simply did not have a PreAmp for recording from home and a solid, always reproducible sound for in-ear monitoring in the rehearsal room and on stage.

Info: I play a passive fender jazz bass, music style punk with pick

From the sound, I would easily describe the SpectraDrive tube.
He makes him a little tense and warm, actually pretty nice. But it starts to rush a bit when you overdo it with the volume. Solo I find the sound that the thing produces super, but had the problem that he can not prevail in the mix with the band properly.

To the EQ:
Actually I find a nice idea with this Smart EQ
Bass: -24db @ 50Hz to + 24db @ 80Hz
Lo mid: -12db @ 200Hz to + 12db @ 160Hz
Hi mid: -18db @ 630Hz to + 18db @ 800Hz
Treeble: -24db @ 1800Hz to + 24db @ 2800Hz

That means at 12 o'clock the EQ regulators do nothing and as soon as you turn them to the left you take frequencies away and at night right others are boosted. Of course you can vary the sound very nicely. Unfortunately, you can only boost certain frequencies, which I would like to take away and vice versa. I have a fender jazz bass and it sounds unbelievably blaring at 800Hz, I normally like to take that frequency out, but it can only amplify it by 3x with the SpectraDrive ... But that may be different with other basses and playing styles. Would be the madness if you could freely prove the frequencies of the pots ...

To the Spectracomp:
It is indeed the complete Spectracomp technology installed in the PreAmp and this can also be occupied via the TonePrint app. Unfortunately only with ready-made TonePrints of TC or their artists. It can not be created as with the actual Spectracomp an individual TonePrint with own settings ...
I had already expected that!
I have dealt with the very friendly and good support from TC.
According to them, this feature is not provided, but you will forward the request to the development department. So maybe it's possible to create your own TonePrints someday ...
The prefabricated are in my opinion, unfortunately not all that really useful, as they are always provided with a car gain, the ausfadende tones can swing unnatural again.

The TubeDrive:
Again freely assignable with the TonePrints of TC. Unfortunately, I find them all unusable ... either too violent, that the Cabinet goes flying or just so vintage sound imitated that could be nice for other bassists. But unfortunately nothing for me

To the connections:
Input, Out and Thru as jack 6.3mm so standard
DI Out with XLR
The DI Out can be switched to either Pre or Post EQ and effects. There is a groundlift and what I find very useful is adjusting the output level of the line or instrument.
Aux IN + Headphones OUT for direct play on the headphones and to play with songs from the Ipod or similar. Super cool feature, if you do not want to practice a bit at home or on the road with interface and cabling action.

The power adapter that is included in the delivery makes a very high quality impression, comes with a swap connection for German sockets and for UK.
It does not growl at all, not even on other pedestrians. As I said very well, also sits great in the socket and does not wobble and is not too clumsy.

The processing of the case is very valuable and makes a solid impression. Also pretty chic in the Matt Black.


Super cool part with very thoughtful and practical features and good sound.
If TC unlocks even more options on the TonePrint app, the device is unbeatable!
