All user reviews for the C Tech Pocket Rock It S1B Bass

Gray and Blue, computer mouse sized mini headphone amp. Comes with a headset that is barely adequate for the device. My Schecter active bass works well with it, as will even passive basses. I love Rock, from classic to metal/industrial and recently got back my bass groove.

I bought this little gem at my local GC because it looked like a good addition for my gig bag. I paid $40.00 for it.

Plugs into the bass directly with a 90 degree swivel jack to allow adjustable access to the controls. It has an on/off switch with an LED, a filter EQ slider,and a volume slider. Also has a dual position switch to choose the sound you bass gets : Big/Tite. I love the compact size, it does what it's supposed to do
it has a line in for an MP3 player to jam along for practice, and a line out for the headset. Once you get the controls set to sound good (takes some practice) you are good to go, at work, in the car, in your room, or at the beach...you can play anywhere, without disturbing anyone. Getting your groove on when you can't use an amp is awesome!
I found that setting the filter about half way, and in the Tite setting, using the active EQ and controls on my bass, I get a great sound.

The headphones it comes with are not adequate for decent volume. I replaced mine with an Audio Technica headset, at 16 ohms, they give you better volume and sound than the supplied headset. If you want to jump around while you play, you may hear some crackling noises from the jacks, not at all pleasant. Getting the 9 volt battery into the very tight compartment is a challenge, but I found that applying equal pressure with both thumbs to slide it into locking position works. The 'Big' setting can get muddy, so I prefer 'Tite'.

All but the jack plug is plastic, and seems very flimsy. Especially nerve racking is that battery cover, but now I can live with it having figured out the trick to getting it to close with a battery in it. The sliders can get crackly too, but once set, are not a problem. Hey, it's forty bucks, and by no means Pro gear...but it does the job when you can't use an amp to practice. The sound is really good once you get it where you want it.

If you need to practice without disturbing anyone, or want to jam along with a cd player or your mp3's just about anywhere, the Pocket Rock-Tt is for you. In spite of it's quirks, and shortcomings, it still does what it was designed to do, and in my opinion...well worth the 40 bucks I paid for it! I use it often, and it keeps working.

I've been using it for two days.

I wanted a bass Vox Amplug but it seems it's still not available yet.

I bought a bass at the same time so I got a discount!

It's sold without a battery but with headphones instead.

To be honest, the manufacturing quality is very bad. The blue plastic housing looks awful and it is not properly assembled. I had to deform a corner of the battery to get it inside the battery compartment...

The device has a volume control and a filter button which seems to be a low-pass filter. I guess it's useful for noisy bass guitars. I set it to the minimum.

The unit also has a 1/8" jack input for an MP3 player for example but the corresponding cable is not provided.

What about usability?

Something very good is that the jack is part of the housing. So it's not an amp you have to carry on your belt, it stays connected directly to the bass.

The swiveling connector can be plugged to any bass.

What about the sound?

Not bad at all. The amp doesn't add noise to the bass signal. Attacks are clearly reproduced. Perfect.

The headphones provided are really cheap. You'd better buy better headphones.

I give it an average mark because of its poor manufacturing quality and the lousy headphone performance.

But once again: the amp sounds very good.
