FenderRumble Stage Digital Bass Modeling Amplifier

Q: Does this amp have a extension speaker jack?

Not really. It has no powered speaker out jack that gets its power from the inboard power out. It has a set of effects in/out stereo jacks that can go to the input of another amp, not an extension speaker unless it's a powered speaker, and XLR jacks that can go to a mixing board, another amp with an XLR input, or a mixing board. If you hook up an ordinary unpowered extension speaker to any of these jacks, you'll get no sound.

Q: Does this amp allow for an active pickup bass?

Absolutely. I’ve got a Fender Deluxe Active Jazz Bass, and they work very well together. Further, there is a very perceptive sound difference when toggling between active and passive, though both modes sound great.

Q: Does this amp require a head, or can i jack in? Can i adjust its settings without an app?

It's fully integrated. Amp, Preamp and Modeling machine all in one. You can adjust settings on the Amp, but I find it easier to change settings using a smart phone, which connects to the amp wirelessly.

Q: Hi, could you tell me the weight and package dimensions?

I'm sorry, but I can't give you the dimensions of the amp in it's shipping carton. I never bothered to check. I was too excited to plug it in and rattle the windows! What I can tell you is this is 800 watts of kick butt amplification, that can be programmed to model specific amp types. I primarily use setting "16," which emulates a big fat Fender Bassman. I play a Hofner 500/1 & a Rick 4001 copy... and the amp just amazing. It weighs 39 pounds. If you don't plan on stacking it in your backline, you can put castors on the bottom & roll it where you need it. It's approx 24 inches tall, 19" wide, with a depth of 14". It's extremely versatile, relatively compact, and has a solid sound. It can rattle your teeth in a small room/stage. I think it's a great value. Hope you enjoy yours.
