A bass amp setup starts with the bass, a cable, and an amp with a speaker that matches how you play. Plug the bass into the amp input, set the EQ flat, and raise the volume slowly. Use headphones through the headphone output when you need to play quietly.
Plug the bass into the amp
Connect the bass to the amp input with an instrument cable. The Fender Rumble 25 has a 1/4 inch headphone output jack and a 1/8 inch auxiliary input jack, and the JOYO MA-10B has an AUX in for external sources such as mobile phones. Start with the amp volume down, then raise it slowly until the bass is audible.
Set the EQ to a flat start
Set the bass, mid and treble knobs to the middle, then adjust one at a time. The Fender Rumble 25 and Rumble 15 both have three band EQ, and the JOYO BA-30 has Bass, Mid and Treble knobs plus a MID FREQ knob. The JOYO MA-10B has a tone control and a drive channel with a gain control for distorted sounds.
Use headphones for quiet practice
Plug headphones into the headphone output when you need to play without sound from the speaker. The Fender Rumble 25 and Rumble 15 both have a headphone output, the JOYO BA-30 has a 3.5mm headphone jack, and the JOYO MA-10B has a connection for headphones. The BA-30 headphone jack gives full-range sound for silent practice.
Add backing tracks over Bluetooth or aux
Play along with music from a phone through the aux input or Bluetooth. The JOYO BA-30 streams backing tracks over Bluetooth 5.1 and records over OTG to phones and PCs with a Type-C connection. The Fender Rumble 25 has a 1/8 inch auxiliary input jack, and the JOYO MA-10B has an AUX in for external sources such as mobile phones.
Power the amp away from a wall
The JOYO MA-10B runs on a power adapter or on batteries, and it plays outdoors for up to three hours on batteries. Outdoors, connect it to a 65W or higher output PD power bank with a 65W high-current USB-C cable.
