Ampeg SCR-DI

Extremely satisfied with this product.
I've been using this D.I. in a studio and live environment and it's just got everything: it's a good D.I., the pre-amp has that Ampeg sound that never gets old, and you can (and should) use the Scrambler, a very dynamic distortion circuit modeled after the classic SVT crunch, to add that little grit that you just need when you make a record. You can also dial it up and get some nice aggression, then blend it in with the clean sound using the knob, but beware cause it tends to get a bit out of control and a little overwhelming in the mid range if you go too far.
It's well made, heavy, sturdy, and esthetically pleasing. The connectors are all top quality and the Aux In and Phones Out can come in handy for practicing and makeshift on-stage monitoring.

PROS:
- Great D.I. if you're looking for that Ampeg sound.
- The Scrambler circuit, properly set, is an invaluable addition to your sound.
- Great construction.

CONS:
- If you want flexibility, go for a SansAmp.
- If you're looking for a more controlled, heavy distortion, take a look at the Darkglass stuff.

It works great and colors the tone wonderfully.
The ultra low is very useful to get a big warm sound and stay out of guitar frequencies.
The ultra high adds bite.
The EQ is solid and usefull.
Plugging headphones or computer speakers into it makes it a great practice amp replacement, and aux in adds further features like playing along with music from your phone or computer.

The drive is ok, not great. Its mid sounding and bites. Very vintagey and fuzzy. You might like it or not

There is one problem. If you have a very hot output you will clip the preamp. There is a trim pot inside the pedal to adjust it but makes the preamp much lower volume than bypass, which must be compensated by either upping the volume of the preamp or leaving the trim pot in passive mode and lowering input volume on the bass or i do it with an compressor. Problem comes around only with VERY HOT output active basses, but it is there.

I recommend the product very much.

I bought this pedal so that I would be able to leave my head&cabin at home when gigging and it turned out to be an excellent buy.

For this low price I got the characterestic Ampeg tone along with an equaliser and an amazing overdrive as well. The overdrive effect is actually so good that it justifies the purchase itself. In addition, using that pedal as my personal DI box enabled me to carry my sound even at the most barebone gig setups. The quality build is very high and I really don't have anything bad to say.

Long story short, as a bass player it is always trouble carrying my amp around small venues, only to find out that the sound engineer or the stage won't allow the use of it. This amazing pedal solves all these problems and doubles as a great overdrive pedal if you feel like it.

Very useful to widen the frequencies of your sound.
You have all the characteristics of a DI box plus two circuits (the clean sound and the overdriven one) which give you the possibility to switch (through the bypass) among three different sound while you are playing.
The clean sound with bass, mid and low filters it's like you had another amp to regulate as you prefer; further, you have two filters (Ultra Lo, to add more body and punch - Ultra Hi to add more definition): in this circuit you recognize the master tone of ampeg amplifiers.
If you want to overdrive the signal you can use the scrambler channel, that allows to decide the amount of drive and the mix with the clean tone.
I do not appreciate the scrambler (overdriven signal) when it's plugged in directly to the audio interface (too much mid frequencies).
I use it mainly through the clean channel, to record in studio, and it gives me a very full, clear sound.
