Shopping malls, paddleboats, pianos, and Ferrari automobiles are all Italian creations. Just try to think of our world had these inventions been limited to the confines of Italy’s borders! While the brand GR Bass is not as notable as Ferrari, musician and engineer Gianfranco Rizzi’s amps have been used by discerning players in Europe since his Italy-based company’s inception in 2015. They’re now available in the U.S., so we tested the Bass ONE800 head paired with a GR 212 cab.
Potenza dei Bassi
The ONE800 has a streamlined appearance and conservative weight at about 5 pounds, keeping it well within the backpack club of compact bass heads. The controls are plentiful and powerful, with a full compliment of EQ adjustability to really fine-tune tone.
The layout is pretty straightforward, with a few treats thrown in for good measure. All the usual refinements are in place, including dials for gain, 4-band EQ, and master out. GR has included frequency switches for mid-lows (185 Hz, 375 Hz, 800 Hz) and mid-highs (600 Hz, 1,200 Hz, 1,800 Hz). There are deep and bright switches that will boost the signal +5 dB at 50 Hz and +6 dB at 9.6k, respectively. I also appreciate the easily accessible aux-in, 1/8" headphone jack and dedicated headphone volume control, and the mute switch, for true silent practice.
Around back, the necessities are in place, with an XLR out (pre- and post-EQ selectable), effects send and return, and dual Speakon connectors. The kicker is a 9V power supply at 300 mA that can power four to five pedals. This is great for players who don’t use a ton of outboard gear, and because the ONE800 also boasts an onboard tuner, there’s room for one more stomp!
