Fender Bassman 100T Tube Bass Amplifier

Powerful, innovative and versatile for stage and studio alike, the Bassman 100T is a professional-level 100-watt tube head with enormous Fender bass sound and sparkling vintage Fender looks. Its dual-channel design uses modern technology to maximize classic technology, with classic Fender '60s "blackface" styling and a wealth of innovative features on the front and rear panels.

Features include a tube preamp (two 12AX7s) and power amp (one 12AT7 and four 6L6s); Vintage channel that delivers the full, warm sound of a classic Fender passive tone stack; Overdrive channel that delivers the aggressive and responsive sound of a modern active tone stack (choose between channels with included footswitch); rear-panel Fender Automatic Bias system that constantly monitors and re-biases tubes for perfect performance and alerts you when service is required; XLR output that delivers overdriven power amp tone (great for recording); rear-panel Output Power switch that lets you play or record at full 100-watt power, quieter 25-watt power, or silently via internal power soak (which captures the signal post-power amp); impedance switch (8, 4 or 2 ohms) and master volume with push/pull mute.

Visually, the amp is very sleek and classy-looking. Structurally, it feels very solidly-built, with no rattling parts of any kind. I plugged mine into a 4ohm 4x10 Fender Rumble Cabinet (the previous iteration, not the newer 8ohm V3 version), and started working the dials. First of all, it is worth noting that you should start the Vintage Channel EQ at Fender's classic flat setting, where the Bass and Treble controls are both at 1, and the Mid at 10. That's a good starting point from which you can boost and cut to taste. My only modification to that setting was to activate the "Deep" circuit by pulling up the Bass pot to boost the low end and mellow the midrange a little. I also set the Channel Volume control at "10", and used the Master Volume to keep me at bedroom playing level. Playing a Fender Precision Bass Special with P/J pickups, I got a warm, vintage tone with just the right amount of Midrange to cut through the mix. Think late 60's/early 70's stuff. Rolling the tone dial back on my bass gave me a really nice Motown vibe. Switching to the Overdrive channel, again I set my Gain and Channel Volume at 10, while still controlling my output with the Master control. I left the Blend control at 1, and started with the EQ flat at 6 across the board. From there, I pulled up the Bass pot to activate the Deep circuit, set the Mid sweep at 5, with the level set at 7, and boosted the Treble control to 8. This gave me a punchy, modern, read more semi-scooped tone which, at band practice, allowed me to fully support the low end and allow the guitars to occupy most of the mid space. For a little more overdrive grit, I simply boosted the Blend control by one notch. Really, really nice stuff.Overall, I am very pleased with the amp. It's rugged, looks professional and sounds great! Plus, it held its own VERY well against two loud guitarists and an equally loud drummer. At one point, with my volume set at just under 5, I was actually too loud. If you're trying to decide between this or something louder, give some serious thought to the venues in which you expect to play. For most of us, my gut says this amp will provide more than enough power - especially with PA support.My ONLY real complaint about this amp is the "Dogbone" carry handle that Fender uses. DO NOT, I REPEAT, DO NOT try to carry this amp by that handle alone. It is cheap and will likely break under the amp's weight if you use it for too long. If you do some research on these Dogbone handles, you will find may other people have found this out the hard way. When carrying the amp, always use the spring-loaded side handles. Cheap carry handle aside, this is a very nice amp that's worth considering.

One of the coolest and most useful features on this amp is the ability to switch from full power at 100 watts to 25 watts for lower volume playing. Adding more bang to your buck is the 25 watt "Silent" setting, which allows you to record directly into a console with the warm tone of both the preamp AND power tubes!

Built like a tank!

A little pricey, in my opinion, but good deals can be found if one is persistent.
