Although the AMP1 was developed for use with a standard guitar, you can also use it with an electric bass. That said, with 100 watts of power, the AMP1 simply has too little power for use with a loud band on stage when used as a bass amp. For at home or when recording, however, you can achieve very cool results with the AMP1 and pimp the bass sound so that it cuts through the mix particularly well.
The Nanotube in the AMP1 creates a beautiful overtone structure and gives the instrument character. The AMP1 signal is therefore ideal for mixing with a signal recorded with a bass amp (or a direct DI signal). Depending on the channel used on the AMP1, you can either make the sound dirtier and/or thicker or give it more assertiveness and attack.
In the following video we recorded some examples for you with the AMP1 Mercury Edition that show how to mix the AMP1 sound to a direct sound:
Incidentally, the REC OUT of the AMP1 is ideal for recording bass. The bass sounds in the video are all recorded with the REC OUT.
Be careful!
If you connect cabinets to the AMP1, please always pay attention to the impedances. Some bass cabs are 4 ohms or less. Please do not connect these to the AMP1 - at least not if the MASTER of the AMP1 is turned up further than 4, because then the protection circuit of the AMP1 is activated, which leads to dropouts.
