There are three features that really stand out on the RH750. The Spectracomp is a solid compressor for slappers, or those who desire more sustain in their sound. The Tubetone is pretty accurate in its intentions, and it is one of the better tube emulators on the market. The Memory buttons are very useful, particularly for bassists who require different settings for their pickups or instruments.
The RH750 has some great qualities, but there are some minor concerns. The LEDs that indicate knob positioning are great for dark stages, but I question how well will they will hold up for the long-term. If TC Electronic trusts the LEDs, they may be better suited on the Master control. The plastic Input jack held up well during testing, but I felt somewhat leery about the durability.
Running With The RH750
To gauge the sound of this mighty amp, I compared the RH750 with class D amplifiers from a variety of other brands. All amps were paired with a variety of cabinets, including the RS212.
Contrasted with its counterparts, the RH750 has a strong midrange presence with solid lows and smooth highs. These characteristics were beneficial in live settings, and fellow soundmen lauded at how well it sat in the mix. I appreciated the ease of adjusting the EQ settings with my different basses, and storing those settings with the memory buttons was invaluable when switching instruments at a gig.
Players who favor their bridge pickup will enjoy the RH750. It enhanced the barks and bumps of my 1964 J bass, and delivered harmonics with plenty of clarity. Slappers may find the highs a little shy, but “glassiness” can be attained with a few tweaks of the Treble knob.
The dark tones of a Nash P bass came out smoothly through the RH750 and the RS212. I had fun manipulating the Tubetone, exhuming a bit of old-school flavor. Maxing out the aforementioned knob created some burly overdrive.
Combined with my Fishman-equipped upright, it had strong low-mid presence, yet it was not quite as responsive as other amps in its class. Even with the Spectracomp turned up, it felt like every time I would play higher passages, the sound would get lost. It also lacked in producing the “wood” of my bass, but this certainly may not be the case for other uprights and pickups.
I was very impressed with the volume. Rated at 750 watts at 4Ω, it held its sonic ground against rock ensembles and big bands. Rarely was it necessary go past 12 o’clock on the Master control.
The RS212 was a smooth sounding cabinet, though it was not the deepest or brightest of the bunch—but adding another cabinet resolved the need for some additional lows. Those who dislike tweeters will appreciate how the coaxial driver delivers the highs, and adjusting the Tweetertone excels at enhancing high frequency content. The RS212 handled a Stingray’s low B adequately, but it struggled a bit when pushed to louder volumes.
TC Electronic has created a series of amplifiers and cabinets that have the most important needs of the bassist in mind. Their thoughtful designs are great for players on the go, and their unique cabinets allow the user to easily hear their instrument while playing with an ensemble. Its tonal character may not be for every bassist, but those who desire more modern sounds may like its personality. If you are looking for a clean tone and a unit that is loaded with features, the TC Electronic RH750 and RS212 are worth the audition.
