Used bass amp that has a few minor scuffs from handling, but generally is in excellent condition. Recently tested and approved!
Here are some specs sprinkled with marketing hype from the manufacturer:
TC Electronic RH450 450-watt Bass Amplifier Head at a Glance:
Powerful and portable
The 450-watt high-power output level of RH450 is accomplished by using Class D amplifier technology in combination with TC Electronic's Active Power Management (APM). APM effectively means that the amp behaves very much like a tube amp when getting close to maximum performance by optimizing the power impact. This is contrary to the hard-clipping tendencies of transistor amps and most other Class D amps. And this head is incredibly portable, too!
Rehearsal inputs and integrated tuner
Playing any instrument on its own can be a little dull, but everyone needs time to practice, which is why RH450 has rehearsal inputs. This rear panel-mounted feature allows you to plug in your iPod, phone, computer, or MP3 player via the supplied mini jack to RCA cable adapter for easy practicing and playing along with recorded music. The headphone amp is a high-quality model taken straight from TC Electronic's Studio Konnekt 48 and includes a speaker filter on the bass signal. The onboard tuner is amazingly convenient. Simply push the mute button to get a full-resolution tuner light ring to help you tune your instrument quickly and accurately. You can also use the RebelControl for easy remote access to this functionality.
User memories and direct outputs
You might not use presets, but only because you've never had the chance! Anyone who's used different basses onstage knows that a few user memories on your amp would be welcome. With RH450, you can easily switch between, for example, your 4- and 5-string basses or your Rickenbacker and Fender Jazz. Just plug in the bass, and use the car radio-style store and recall controls to easily switch between presets for your chosen model. There are three bass user memories, remote control access, and visual indicators for mute and the tuner. A transformer-balanced line-out gives you stellar live-sound DI and direct-recording performance - even with long cable runs! Speaking of direct recording, a built-in AES/EBU connector lets you plug straight into your DAW.
Straightforward but incredibly versatile tone controls
The RH450 features straightforward controls much like those you'd find on traditional amp, voiced to give you plenty of tweaking options to nail the perfect tone. Chances are, this is all you're ever going to need. However, if you're not fully satisfied with the default frequency areas, fear not - TC Electronic has given you the option to change the focus of each of the tone controls. This functionality allows you to pinpoint a frequency you either want to remove or boost for each tone control, and then store the settings.
TubeTone and Spectra Comp
Most transistor designs have tried to replicate the tube sound using one small preamp tube, but they generally fail because they don't take into account the crucial characteristics of the full preamp and power amp sections - both of which are essential to the sound. TubeTone emulates all characteristics to deliver the full tube sound. Likewise, integrated compressors generally don't sound that good. A regular compressor tends to be dominated by the lower string, but RH450's SpectraComp technology allows virtually per string multiband compression that evens out the compression across all strings.
