Bass Amp Purchase - Part 2

(Continued from Part 1)

EQ – Equalization can be graphic, parametric, semi-parametric, or a variety of combinations. What suits you? Usually shop staff are knowledgeable and will assist.

Compression – Most high-end bass amps have good in-built compressors. A touch of compression is not to be overlooked in your sound. All recordings have a degree of bass compression and it is an excellent asset for live playing too. (All of my lessons are recorded with bass compression. Have you noticed? If not, that’s good. Online Bass Lessons are available at CreativeBassLessons.com)

If you purchase separate pre-amp, power amp and speakers, you can always mix and match. This is a great way of achieving your ultimate sound. You can try tube/solid state amp combinations with speakers and speaker cabs of various sizes and quality.
Many amp heads now have the option of blending tube and solid state pre-amps. Some do amp simulation (of well-known and successful combinations) too. This will enable you to find out what is most suitable.

My current setup (for the past 12 years) is an amp head containing two 250W power amps plus all the other shbang such as DI with output control, a good compressor, semi-parametric EQ, shelving (graphic) EQ, headphone jacks, tuner and effects in/out plus more. And very importantly, a tube pre-amp. This makes the amp sound better as it warms up. I run both power amps into bridged mono, giving me 600W RMS into a 350W RMS 2x10 speaker cab with an attenuateable horn. The cab can handle peaks of up to 800W.

A note on speaker cabs – 2x10 has approx. the same surface as a 1x15 speaker. Therefore the 2x10 has a similar amount of bass depth as the 1x15, yet a better, faster, clearer response, making it fine for 5-string basses.

Although the info provided above might seem in-depth, it is not really. Many issues have not been mentioned. I trust I have provided you with enough insights to get you onto YOUR path.
