Ultra-portable Micro Amp Packed with Powerful PJB Tone Building upon Phil Jones Bass's fan-favorite BG-75 Double 4 formula, the BG-80 Double 4 Plus elevates the micro-bass-amp format to soaring new sonic heights. This 90-watt bass amplifier's dual “Long-thro” 4-inch speakers supply a seriously powerful and chest-thumping level of bass that defies the BG-80's grab-and-go format. Plus, these speakers are equally capable of delivering full-range performance across the frequency spectrum — you'll enjoy full-fidelity backing tracks and tunes when you pair your device with the BG-80's aux input and onboard Bluetooth connections. Plus, you get a powerful 3-band EQ to sculpt your sound, High/Low input options to accommodate active and passive basses, a line output, and a USB-C DC input that enables cord-free power bank performance. And did we mention that this ultra-compact bass amp can take on frequencies down to the low-B on a 5-string without breaking a sweat? Whether
