The Bassman 300 PRO captures the all-tube vibe and combines it with modern features. Six 6550 power tubes deliver a world tour-ready 300 Watts (into 2, 4, or 8 Ohms). Other features include two 12AX7 preamp tubes, two channels (clean, dirty with blend), 10-band graphic EQ with on-off switch, low- and high-frequency boost switches, mid-notch switch (great for slap playing), line out switch (for selecting pre or post EQ), two-band compressor with EQ balance and gain trim, effects loop, power amp pass-through output jack (for chaining multiple units together), balanced XLR and 1/4" output jacks (post EQ and effects loop), tuner out jack with mute switch, and three-function footswitch.
