The Revelation Serena

One channel, two knob, low-power amp for you to be able to crank up and get full power tube big-volume glory without waking the neighbors.  Perfect for studio work (especially home studios) or in any other environment where loud is a bad word, such as coffee houses, at home practice, church worship bands, playing along with unamplified piano or acoustic ensembles, etc.

Pictures coming soon!  We are currently waiting on the face plates to come in before we can shoot the pictures.  Serena is styled like a 72 only with a lot less knobs and uses the same cabinet, so for now, you might look at the 72 page for approximate pictures.

SOUNDS
Recorded all guitar tracks with just the Serena combo using a 12AT7 power tube.  All tracks are 192K mp3s and run from 2-5 minutes each.  These tracks are recorded with my personal guitars, which include a Fender Esprit with DiMarzio PAFs, an SG copy with DiMarzio PAFs and a Fender Telecaster with Duncan pickups.

Studio Clip Lead Guitar Rhythm Guitar Mic Notes
Olive Tree Studio High Voltage Esprit SG + Esprit SM57 The double-track rhythm guitar is a staple of rock guitar recording. The left side rhythm track was recorded with the "Voice" switch in the "Rock" position and the right side track with the Voice switch in the "Blues" position. The lead track was recorded with the Voice switch in the "Rock" position.
Olive Tree Studio Chevy Shuffle Tele, Esprit Tele MD-421 Voice switch "Blues" for all tracks
Olive Tree Studio Texas Blues Esprit Esprit SM57 Note the touch-sensitivity in this track.  All of the tracks were performed as one continuous take, without any amp adjustments during the take.  Serena cleans up nicely with the volume control down, and gets gritty and chewy when you dig in. Even when very quiet, the tone is rich and full.
Olive Tree Studio Anglo Pop Esprit SG + Tele SM57 In this clip the "top boost" kind of character really shows up.  The Serena will get very bright if you want her to, especially with single coils. This clip really showcases the dynamic resposnveness and texture of the Serena. The tracks were all continuous takes without punches, and no changes of guitar or amp controls during the take, just picking dynamics. 
BOSS Micro BR Bossy Esprit Esprit PVM 380N This clip demonstrates how Serena is not just a rock/blues amplifier. This little jazz tune was recorded quick & dirty at my house using the Serena in "rock" mode on both the lead and rhythm tracks.
BOSS Micro BR B-Rock 1 SG SG + Tele PVM 380N Lead guitar, rock voice with a clean boost pedal
BOSS Micro BR B-Rock 2 SG SG + Tele PVM 380N Lead guitar, blues voice with a TS-808 Tube Screamer pedal
BOSS Micro BR B-Rock 3 SG SG + Tele PVM 380N Lead guitar, rock voice with the Serena "Hot Rod" mod
BOSS Micro BR B-Rock 4 SG SG + Tele PVM 380N Lead guitar, rock voice with the Serena "Hot Rod" mod and a clean boost pedal
BOSS Micro BR B-Rock 5 SG SG + Tele PVM 380N Lead guitar, rock voice with a TS-808 Tube Screamer and a wah pedal
BOSS Micro BR B-Rock 6 SG SG + Tele PVM 380N Just the bass, drums, and rhythm guitars, of course with Serena
Olive Tree Studio Rough Mix Clips - - - This little montage is from a recording session for an album project using a Serena on all of the guitar tracks.  The guitars and mics here vary.  All of the tracks are the Serena.  This is a quick & dirty rough mix of incomplete arrangements.

Olive Tree Studio tracks were recorded with a Yamaha PM-1000 channel strip and a MOTU 1224 audio card direct to Nuendo.  There were no pedals or effects of any kind on these guitar tracks. Some reverb and delay may be added at mixdown.

BOSS Micro BR tracks were recorded in my home with a Boss Micro BR digital 4-track and no outboard gear, with a Peavey PVM 380N microphone, and then mixed with Reaper on a PC.  They also have some reverb and delay added at mixdown.  This is total cheapskate recording!

The Serena Concept

We all know that tube amps sound best when they are cranked. It's one thing to build an amp that sounds great when cranked, to heck with the neighbors. It's quite another to have an amp that you can turn all the way up so that it sounds great, and then play at home in your apartment without having a visit from the landlord or the police. The Serena is a simple, pure-bred tube guitar amp with all of the big, fat tone of a big, fat cranked amp, only without the decibel hangover and frowns from the sound man.

How it Works

Most small guitar amps built for bedroom use or practice are indeed small and sound small. There are two reasons why they sound small. Reason #1 is the speaker. Many have found that the tone of an old "Champ" or other little amp improves greatly when you plug it into a real cabinet with a 12" speaker.

The Serena combo uses the same full-size cabinet as the big & bad 72, loaded with a Revelized* 12" speaker, to get over this "it's small, so it sounds small" hurdle.

The other reason is a lot more technical. Most small tube amps are single-ended amps, while most big amps are push-pull amps.

Say what?

A push-pull guitar amp uses two power tubes, one to amplify one half of the wave form, and one to amplify the other half (one positive, one negative).  A push-pull amp also requires an extra preamp stage called a phase inverter, which imparts its own sonic character.  This out-of-phase, somewhat-balanced relationship between the opposing power tubes causes some harmonics to get cancelled out and some others to be let through when they distort.  There is a distinct sound of two out-of-phase power tubes each making their own distortion. This is a big part of the sound of the classic tube guitar amp.

Most small guitar amps use one power tube to amplify the whole wave. This is called "single-ended".  A prime example is the old "Champ" type amp, and most modern small amps are descendents of this same idea. These amps are kind of like 1/2 of a regular guitar amp, but without a phase inverter. There is only one power tube making distortion, and none of those harmonics get cancelled out. The tone of a single-ended guitar amp is very different than that if a push-pull amp.

The Serena is a small amp built big-amp style. It is a push-pull amp with a phase inverter and the whole shebang. Only instead of using high-power output tubes, it uses a low-power dual-triode tube for the power stage. You get the big-amp sound, at the small-amp volume level.

So How Loud Is It?

Don't get me wrong. This is not necessarily a quiet amp. The Serena will run with one of many dual-triode tubes in the power stage to give it different amounts of power, clean headroom, and tone character.  Also, speakers of different efficiency can be selected for the combo to tune it to taste. With an ECC99 power tube and a 102dB speaker, this is a totally giggable amp for small-venue blues gigs, larger churches, jazz, or just about anywhere that you don't need ear-bleeding levels. Switch the power tube to a 12AT7 and the volume goes right back to spouse-friendly levels.

The Serena combo is available with a choice of speakers to make the amount of clean headroom and cranked volume you need.

The Voice Switch

The Serena has a "Voice" switch on the front panel, that goes from a warm, round tone in the "Blues" position to a more aggressive, brighter tone in the "Rock" position.  Both modes have plenty of gain to get the amp very saturated but the tonal character is not-so-subtly different.  The Serena is touch sensitive and cleans up with the volume control in either Blues or Rock voice.

Different Power Tubes?
Since the Serena uses a standard 9-pin dual-triode for the power tube, you can run multiple different kinds of tubes in it for different tone character, clean headroom, total power and breakup.  Serena was designed to optimally run with a JJ ECC99 tube or a 12AU7.

Revelized speaker
All Serena combos come with a Revelized* speaker for increased low-level sensitivity and suitability for a lower-power amplifier.

The Serena is completely hand-wired and built by hand, one unit at a time.  

The tone-freak's choice for all those times when you don't need a screamin' loud amp.
